Pull pci updates from Bjorn Helgaas:
 "Enumeration:

   - Add PCI_FIND_NEXT_CAP() and PCI_FIND_NEXT_EXT_CAP() macros that
     take config space accessor functions.

     Implement pci_find_capability(), pci_find_ext_capability(), and
     dwc, dwc endpoint, and cadence capability search interfaces with
     them (Hans Zhang)

   - Leave parent unit address 0 in 'interrupt-map' so that when we
     build devicetree nodes to describe PCI functions that contain
     multiple peripherals, we can build this property even when
     interrupt controllers lack 'reg' properties (Lorenzo Pieralisi)

   - Add a Xeon 6 quirk to disable Extended Tags and limit Max Read
     Request Size to 128B to avoid a performance issue (Ilpo Järvinen)

   - Add sysfs 'serial_number' file to expose the Device Serial Number
     (Matthew Wood)

   - Fix pci_acpi_preserve_config() memory leak (Nirmoy Das)

  Resource management:

   - Align m68k pcibios_enable_device() with other arches (Ilpo
     Järvinen)

   - Remove sparc pcibios_enable_device() implementations that don't do
     anything beyond what pci_enable_resources() does (Ilpo Järvinen)

   - Remove mips pcibios_enable_resources() and use
     pci_enable_resources() instead (Ilpo Järvinen)

   - Clean up bridge window sizing and assignment (Ilpo Järvinen),
     including:

       - Leave non-claimed bridge windows disabled

       - Enable bridges even if a window wasn't assigned because not all
         windows are required by downstream devices

       - Preserve bridge window type when releasing the resource, since
         the type is needed for reassignment

       - Consolidate selection of bridge windows into two new
         interfaces, pbus_select_window() and
         pbus_select_window_for_type(), so this is done consistently

       - Compute bridge window start and end earlier to avoid logging
         stale information

  MSI:

   - Add quirk to disable MSI on RDC PCI to PCIe bridges (Marcos Del Sol
     Vives)

  Error handling:

   - Align AER with EEH by allowing drivers to request a Bus Reset on
     Non-Fatal Errors (in addition to the reset on Fatal Errors that we
     already do) (Lukas Wunner)

   - If error recovery fails, emit FAILED_RECOVERY uevents for the
     devices, not for the bridge leading to them.

     This makes them correspond to BEGIN_RECOVERY uevents (Lukas Wunner)

   - Align AER with EEH by calling err_handler.error_detected()
     callbacks to notify drivers if error recovery fails (Lukas Wunner)

   - Align AER with EEH by restoring device error_state to
     pci_channel_io_normal before the err_handler.slot_reset() callback.

     This is earlier than before the err_handler.resume() callback
     (Lukas Wunner)

   - Emit a BEGIN_RECOVERY uevent when driver's
     err_handler.error_detected() requests a reset, as well as when it
     says recovery is complete or can be done without a reset (Niklas
     Schnelle)

   - Align s390 with AER and EEH by emitting uevents during error
     recovery (Niklas Schnelle)

   - Align EEH with AER and s390 by emitting BEGIN_RECOVERY,
     SUCCESSFUL_RECOVERY, or FAILED_RECOVERY uevents depending on the
     result of err_handler.error_detected() (Niklas Schnelle)

   - Fix a NULL pointer dereference in aer_ratelimit() when ACPI GHES
     error information identifies a device without an AER Capability
     (Breno Leitao)

   - Update error decoding and TLP Log printing for new errors in
     current PCIe base spec (Lukas Wunner)

   - Update error recovery documentation to match the current code
     and use consistent nomenclature (Lukas Wunner)

  ASPM:

   - Enable all ClockPM and ASPM states for devicetree platforms, since
     there's typically no firmware that enables ASPM

     This is a risky change that may uncover hardware or configuration
     defects at boot-time rather than when users enable ASPM via sysfs
     later. Booting with "pcie_aspm=off" prevents this enabling
     (Manivannan Sadhasivam)

   - Remove the qcom code that enabled ASPM (Manivannan Sadhasivam)

  Power management:

   - If a device has already been disconnected, e.g., by a hotplug
     removal, don't bother trying to resume it to D0 when detaching the
     driver.

     This avoids annoying "Unable to change power state from D3cold to
     D0" messages (Mario Limonciello)

   - Ensure devices are powered up before config reads for
     'max_link_width', 'current_link_speed', 'current_link_width',
     'secondary_bus_number', and 'subordinate_bus_number' sysfs files.

     This prevents using invalid data (~0) in drivers or lspci and,
     depending on how the PCIe controller reports errors, may avoid
     error interrupts or crashes (Brian Norris)

  Virtualization:

   - Add rescan/remove locking when enabling/disabling SR-IOV, which
     avoids list corruption on s390, where disabling SR-IOV also
     generates hotplug events (Niklas Schnelle)

  Peer-to-peer DMA:

   - Free struct p2p_pgmap, not a member within it, in the
     pci_p2pdma_add_resource() error path (Sungho Kim)

  Endpoint framework:

   - Document sysfs interface for BAR assignment of vNTB endpoint
     functions (Jerome Brunet)

   - Fix array underflow in endpoint BAR test case (Dan Carpenter)

   - Skip endpoint IRQ test if the IRQ is out of range to avoid false
     errors (Christian Bruel)

   - Fix endpoint test case for controllers with fixed-size BARs smaller
     than requested by the test (Marek Vasut)

   - Restore inbound translation when disabling doorbell so the endpoint
     doorbell test case can be run more than once (Niklas Cassel)

   - Avoid a NULL pointer dereference when releasing DMA channels in
     endpoint DMA test case (Shin'ichiro Kawasaki)

   - Convert tegra194 interrupt number to MSI vector to fix endpoint
     Kselftest MSI_TEST test case (Niklas Cassel)

   - Reset tegra194 BARs when running in endpoint mode so the BAR tests
     don't overwrite the ATU settings in BAR4 (Niklas Cassel)

   - Handle errors in tegra194 BPMP transactions so we don't mistakenly
     skip future PERST# assertion (Vidya Sagar)

  AMD MDB PCIe controller driver:

   - Update DT binding example to separate PERST# to a Root Port stanza
     to make multiple Root Ports possible in the future (Sai Krishna
     Musham)

   - Add driver support for PERST# being described in a Root Port
     stanza, falling back to the host bridge if not found there (Sai
     Krishna Musham)

  Freescale i.MX6 PCIe controller driver:

   - Enable the 3.3V Vaux supply if available so devices can request
     wakeup with either Beacon or WAKE# (Richard Zhu)

  MediaTek PCIe Gen3 controller driver:

   - Add optional sys clock ready time setting to avoid sys_clk_rdy
     signal glitching in MT6991 and MT8196 (AngeloGioacchino Del Regno)

   - Add DT binding and driver support for MT6991 and MT8196
     (AngeloGioacchino Del Regno)

  NVIDIA Tegra PCIe controller driver:

   - When asserting PERST#, disable the controller instead of mistakenly
     disabling the PLL twice (Nagarjuna Kristam)

   - Convert struct tegra_msi mask_lock to raw spinlock to avoid a lock
     nesting error (Marek Vasut)

  Qualcomm PCIe controller driver:

   - Select PCI Power Control Slot driver so slot voltage rails can be
     turned on/off if described in Root Port devicetree node (Qiang Yu)

   - Parse only PCI bridge child nodes in devicetree, skipping unrelated
     nodes such as OPP (Operating Performance Points), which caused
     probe failures (Krishna Chaitanya Chundru)

   - Add 8.0 GT/s and 32.0 GT/s equalization settings (Ziyue Zhang)

   - Consolidate Root Port 'phy' and 'reset' properties in struct
     qcom_pcie_port, regardless of whether we got them from the Root
     Port node or the host bridge node (Manivannan Sadhasivam)

   - Fetch and map the ELBI register space in the DWC core rather than
     in each driver individually (Krishna Chaitanya Chundru)

   - Enable ECAM mechanism in DWC core by setting up iATU with 'CFG
     Shift Feature' and use this in the qcom driver (Krishna Chaitanya
     Chundru)

   - Add SM8750 compatible to qcom,pcie-sm8550.yaml (Krishna Chaitanya
     Chundru)

   - Update qcom,pcie-x1e80100.yaml to allow fifth PCIe host on Qualcomm
     Glymur, which is compatible with X1E80100 but doesn't have the
     cnoc_sf_axi clock (Qiang Yu)

  Renesas R-Car PCIe controller driver:

   - Fix a typo that prevented correct PHY initialization (Marek Vasut)

   - Add a missing 1ms delay after PWR reset assertion as required by
     the V4H manual (Marek Vasut)

   - Assure reset has completed before DBI access to avoid SError (Marek
     Vasut)

   - Fix inverted PHY initialization check, which sometimes led to
     timeouts and failure to start the controller (Marek Vasut)

   - Pass the correct IRQ domain to generic_handle_domain_irq() to fix a
     regression when converting to msi_create_parent_irq_domain()
     (Claudiu Beznea)

   - Drop the spinlock protecting the PMSR register - it's no longer
     required since pci_lock already serializes accesses (Marek Vasut)

   - Convert struct rcar_msi mask_lock to raw spinlock to avoid a lock
     nesting error (Marek Vasut)

     STM32MP25 in host and endpoint modes (Christian Bruel)

  Synopsys DesignWare PCIe controller driver:

   - Add support for x16 in devicetree 'num-lanes' property (Konrad
     Dybcio)

   - Verify that if DT specifies a single IRQ for all eDMA channels, it
     is named 'dma' (Niklas Cassel)

  TI J721E PCIe driver:

   - Add MODULE_DEVICE_TABLE() so driver can be autoloaded (Siddharth
     Vadapalli)

   - Power controller off before configuring the glue layer so the
     controller latches the correct values on power-on (Siddharth
     Vadapalli)

  TI Keystone PCIe controller driver:

   - Use devm_request_irq() so 'ks-pcie-error-irq' is freed when driver
     exits with error (Siddharth Vadapalli)

6093a688a0 Merge tag 'char-misc-6.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc
Pull Char/Misc/IIO/Binder updates from Greg KH:
 "Here is the big set of char/misc/iio and other driver subsystem
  changes for 6.18-rc1.

  Loads of different stuff in here, it was a busy development cycle in
  lots of different subsystems, with over 27k new lines added to the
  tree.

  Included in here are:

   - IIO updates including new drivers, reworking of existing apis, and
     other goodness in the sensor subsystems

   - MEI driver updates and additions

   - NVMEM driver updates

   - slimbus removal for an unused driver and some other minor updates

   - coresight driver updates and additions

   - MHI driver updates

   - comedi driver updates and fixes

   - extcon driver updates

   - interconnect driver additions

   - eeprom driver updates and fixes

   - minor UIO driver updates

   - tiny W1 driver updates

  But the majority of new code is in the rust bindings and additions,
  which includes:

   - misc driver rust binding updates for read/write support, we can now
     write "normal" misc drivers in rust fully, and the sample driver
     shows how this can be done.

   - Initial framework for USB driver rust bindings, which are disabled
     for now in the build, due to limited support, but coming in through
     this tree due to dependencies on other rust binding changes that
     were in here. I'll be enabling these back on in the build in the
     usb.git tree after -rc1 is out so that developers can continue to
     work on these in linux-next over the next development cycle.

   - Android Binder driver implemented in Rust.

     This is the big one, and was driving a huge majority of the rust
     binding work over the past years. Right now there are two binder
     drivers in the kernel, selected only at build time as to which one
     to use as binder wants to be included in the system at boot time.

     The binder C maintainers all agreed on this, as eventually, they
     want the C code to be removed from the tree, but it will take a few
     releases to get there while both are maintained to ensure that the
     rust implementation is fully stable and compliant with the existing
     userspace apis.

  All of these have been in linux-next for a while"

86d563ac5f Merge tag 'f2fs-for-6.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs
Pull f2fs updates from Jaegeuk Kim:
 "This focuses on two primary updates for Android devices.

  First, it sets hash-based file name lookup as the default method to
  improve performance, while retaining an option to fall back to a
  linear lookup.

  Second, it resolves a persistent issue with the 'checkpoint=enable'
  feature.

  The update further boosts performance by prefetching node blocks,
  merging FUA writes more efficiently, and optimizing block allocation
  policies.

  The release is rounded out by a comprehensive set of bug fixes that
  address memory safety, data integrity, and potential system hangs,
  along with minor documentation and code clean-ups.

  Enhancements:
   - add mount option and sysfs entry to tune the lookup mode
   - dump more information and add a timeout when enabling/disabling
     checkpoints
   - readahead node blocks in F2FS_GET_BLOCK_PRECACHE mode
   - merge FUA command with the existing writes
   - allocate HOT_DATA for IPU writes
   - Use allocate_section_policy to control write priority in
     multi-devices setups
   - add reserved nodes for privileged users
   - Add bggc_io_aware to adjust the priority of BG_GC when issuing IO
   - show the list of donation files

  Bug fixes:
   - add missing dput() when printing the donation list
   - fix UAF issue in f2fs_merge_page_bio()
   - add sanity check on ei.len in __update_extent_tree_range()
   - fix infinite loop in __insert_extent_tree()
   - fix zero-sized extent for precache extents
   - fix to mitigate overhead of f2fs_zero_post_eof_page()
   - fix to avoid migrating empty section
   - fix to truncate first page in error path of f2fs_truncate()
   - fix to update map->m_next_extent correctly in f2fs_map_blocks()
   - fix wrong layout information on 16KB page
   - fix to do sanity check on node footer for non inode dnode
   - fix to avoid NULL pointer dereference in
     f2fs_check_quota_consistency()
   - fix to detect potential corrupted nid in free_nid_list

   falls to zero

 - "kho: fixes and cleanups" from Mike Rapoport adds a few touchups to
   the recently added Kexec Handover feature

 - "mm: make mm->flags a bitmap and 64-bit on all arches" from Lorenzo

 - "prctl: extend PR_SET_THP_DISABLE to only provide THPs when advised"
   from David Hildenbrand "allows individual processes to opt-out of
   THP=always into THP=madvise, without affecting other workloads on the
   system".

   It's a long story - the [1/N] changelog spells out the considerations

 - "Add and use memdesc_flags_t" from Matthew Wilcox gets us started on
   the memdesc project. Please see

      https://kernelnewbies.org/MatthewWilcox/Memdescs and
      https://blogs.oracle.com/linux/post/introducing-memdesc

 - "Tiny optimization for large read operations" from Chi Zhiling
   improves the efficiency of the pagecache read path

   cgroups of random inappropriate tasks

 - "mm/pageblock: improve readability of some pageblock handling" from
   Wei Yang provides some readability improvements to the page allocator
   code

   the removal of that undesirable helper function

 - "introduce kasan.write_only option in hw-tags" from Yeoreum Yun
   creates a KASAN read-only mode for ARM, using that architecture's
   memory tagging feature. It is felt that a read-only mode KASAN is

   from Lorenzo Stoakes moves us further towards removal of
   file_operations.mmap(). This patchset concentrates upon clearing up
   the treatment of stacked filesystems

 - "mm: Improve mlock tracking for large folios" from Kiryl Shutsemau
   provides some fixes and improvements to mlock's tracking of large
   folios. /proc/meminfo's "Mlocked" field became more accurate

 - "mm/ksm: Fix incorrect accounting of KSM counters during fork" from
   Donet Tom fixes several user-visible KSM stats inaccuracies across
   forks and adds selftest code to verify these counters

 - "mm_slot: fix the usage of mm_slot_entry" from Wei Yang addresses
   some potential but presently benign issues in KSM's mm_slot handling

Pull networking updates from Paolo Abeni:
 "Core & protocols:

   - Improve drop account scalability on NUMA hosts for RAW and UDP
     sockets and the backlog, almost doubling the Pps capacity under DoS

   - Optimize the UDP RX performance under stress, reducing contention,
     revisiting the binary layout of the involved data structs and
     implementing NUMA-aware locking. This improves UDP RX performance
     by an additional 50%, even more under extreme conditions

   - Add support for PSP encryption of TCP connections; this mechanism
     has some similarities with IPsec and TLS, but offers superior HW
     offloads capabilities

   - Ongoing work to support Accurate ECN for TCP. AccECN allows more
     than one congestion notification signal per RTT and is a building
     block for Low Latency, Low Loss, and Scalable Throughput (L4S)

   - Reorganize the TCP socket binary layout for data locality, reducing
     the number of touched cachelines in the fastpath

   - Refactor skb deferral free to better scale on large multi-NUMA
     hosts, this improves TCP and UDP RX performances significantly on
     such HW

   - Increase the default socket memory buffer limits from 256K to 4M to
     better fit modern link speeds

   - Improve handling of setups with a large number of nexthop, making
     dump operating scaling linearly and avoiding unneeded
     synchronize_rcu() on delete

   - Improve bridge handling of VLAN FDB, storing a single entry per
     bridge instead of one entry per port; this makes the dump order of
     magnitude faster on large switches

   - Restore IP ID correctly for encapsulated packets at GSO
     segmentation time, allowing GRO to merge packets in more scenarios

   - Improve netfilter matching performance on large sets

   - Improve MPTCP receive path performance by leveraging recently
     introduced core infrastructure (skb deferral free) and adopting
     recent TCP autotuning changes

   - Allow bridges to redirect to a backup port when the bridge port is
     administratively down

   - Introduce MPTCP 'laminar' endpoint that con be used only once per
     connection and simplify common MPTCP setups

   - Add RCU safety to dst->dev, closing a lot of possible races

   - A significant crypto library API for SCTP, MPTCP and IPv6 SR,
     reducing code duplication

     XDP buffer

  Things we sprinkled into general kernel code:

   - Generate netlink documentation from YAML using an integrated YAML
     parser

  Driver API:

   - Support using IPv6 Flow Label in Rx hash computation and RSS queue
     selection

   - Make XDP helpers compatible with unreadable memory, allowing more
     easily building DevMem-enabled drivers with a unified XDP/skbs
     datapath

   - Add a new dedicated ethtool callback enabling drivers to provide
     the number of RX rings directly, improving efficiency and clarity
     in RX ring queries and RSS configuration

   - Introduce a burst period for the health reporter, allowing better
     handling of multiple errors due to the same root cause

   - Support for DPLL phase offset exponential moving average,
     controlling the average smoothing factor

  Device drivers:

   - Add a new Huawei driver for 3rd gen NIC (hinic3)

Pull power management updates from Rafael Wysocki:
 "The majority of these are cpufreq changes, which has been a recurring
  pattern for a few recent cycles.

  Those changes include new hardware support (AN7583 SoC support in the
  airoha cpufreq driver, ipq5424 support in the qcom-nvmem cpufreq
  driver, MT8196 support in the mediatek cpufreq driver, AM62D2 support
  in the ti cpufreq driver), DT bindings and Rust code updates, cleanups
  of the core and governors, and multiple driver fixes and cleanups.

  Beyond that, there are hibernation fixes (some remaining 6.16 cycle
  fallout and an issue related to hybrid suspend in the amdgpu driver),
  cleanups of the PM core code, runtime PM documentation update, cpuidle
  and power capping cleanups, and tooling updates.

  Specifics:

   - Rearrange variable declarations involving __free() in the cpufreq
     core and intel_pstate driver to follow common coding style (Rafael
     Wysocki)

     core to simplify the initial policy path (Zihuan Zhang)

   - Clean up the cpufreq core in multiple places (Zihuan Zhang)

   - Use int type to store negative error codes in the cpufreq core and
     update the speedstep-lib to use int for error codes (Qianfeng Rong)

For some coresight components like CTI and TPDM, there could be
numerous of them. From the node name, we can only get the type and
register address of the component. We can't identify the HW or the
system the component belongs to. Add label sysfs node support for
showing the intuitive name of the device.

IIO: New device support, features and cleanup for 6.18

New device support
==================

ad,ade9000
- New driver for this complex energy and power monitoring ADC.
infineon,tlv493d
- New driver for this 3D magnetic sensor.
intel,dollar
- New driver for this TI PMIC (part number unknown)
marvel,88pm886
- Driver for this PMIC ADC.
microchip,mcp9600
- Add explicit support for the mcp9601 which has some additional features
  over the mcp9600.
rohm,bd79112
- New driver for this ADC / GPIO Chip.

Features
========
Core
- New helper to multiply data expressed in IIO types.
- Add KUnit tests.
- New IIO_ALTCURRENT type, similar to existing IIO_ALTVOLTAGE
- Add some channel modifiers related to energy and power, such as
  reactive.
adi,ad7124
- Support external clocks sources and output of the internal clocks.
- Filter control.
adi,ad7173
- Add filter support. Some fiddly interactions with other parameters on this
  device.
adi,ad7779
- Add backend support which required control of the number of lanes used.
liteon,ltr390
- Add runtime PM support.
microchip,mcp9600
- Add support for different thermocouple types.

Cleanup and minor fixes
=======================

core
- Switch info_mask fields to be unsigned. Not clear why they were ever
  signed.
- Fix handling of negative channel scale in iio_convert_raw_to_processed()
- Fix offset handling for channels without a scale attribute.
- Improve the precision of scaling slightly.
- Drop apparent handling of IIO_CHAN_INFO_PROCESSED for devices that don't
  have any such channels.
various
- Drop many pm_runtime_mark_last_busy() calls now
  pm_runtime_put_autosuspend() calls it internally.
- Drop dev_err_probe() calls where the error code is hard coded as -ENOMEM
  as they don't do anything.
- Drop dev_err() calls where the error code is -ENOMEM. This will reduce
  error prints, but memory failures generate a lot of messages anyway
  so unlikely we need these prints.
current-sense-amplifier
- Add #io-channels property this channel to be used by a consumer driver.
adi,ad7124
- Fix incorrect clocks dt-binding property.
- Make the mclk clock optional in DT - this is internal to the ADC so should
  never have been in he binding.
- Fix up sample rate to comply with ABI.
- Use read_avail() callback rather than opencoding similar.
- Deploy guard() to clean up some lock handling.
adi,ad7768
- Use devm_regulator_get_enable_read_voltage() to replace similar code.
adi,ad7816
- Drop an unnecessary dev_set_drvdata() call as nothing uses the data.
ad,adxl345
- Fix missing blank line before bullet list in documentation.
arm,scmi
- Use devm_kcalloc() for an array allocation rather than devm_kzalloc().
bosch,bmi270
- Match an ACPI ID seen in the wild. It is not spec compliant but we can't
  do much about that.
bosch,bmp280
- Drop overly noisy dev_info()
- Allow for sleeping gpio controllers.
gogle,cros-ec
- Drop unused location attribute that has been replaced by label.
invense,icm42600
- Simplify the power management.
- Use guard() to simplify some locking.
maxim,max1238

  consumer.
microchip,mcp9600
- Specify a default value in dt-binding for the thermocouple type
- General whitespace cleanup.
samsung,exynos
- Drop support for the S3C2410 including bindings, and touchscreen support
  as nothing else uses that.
- Drop platform ID based binding as not used.
st,vl53l0x
- Fix returning the wrong variable in an error path.
ti,pac1934
- Replace open coded devm_mutex_init().
xilinx,ams

On systems with multiple GPUs there can be uncertainty which GPU is the
primary one used to drive the display at bootup. In some desktop
environments this can lead to increased power consumption because
secondary GPUs may be used for rendering and never go to a low power
state. In order to disambiguate this add a new sysfs attribute
'boot_display' that uses the output of video_is_primary_device() to
populate whether the PCI device was used for driving the display.

b639c20e74 f2fs: Use allocate_section_policy to control write priority in multi-devices setups
Introduces two new sys nodes: allocate_section_hint and
allocate_section_policy. The allocate_section_hint identifies the boundary
between devices, measured in sections; it defaults to the end of the device
for single storage setups, and the end of the first device for multiple
storage setups. The allocate_section_policy determines the write strategy,
with a default value of 0 for normal sequential write strategy. A value of
1 prioritizes writes before the allocate_section_hint, while a value of 2
prioritizes writes after it.

This strategy addresses the issue where, despite F2FS supporting multiple
devices, SOC vendors lack multi-devices support (currently only supporting
zoned devices). As a workaround, multiple storage devices are mapped to a
single dm device. Both this workaround and the F2FS multi-devices solution
may require prioritizing writing to certain devices, such as a device with
better performance or when switching is needed due to performance
degradation near a device's end. For scenarios with more than two devices,
sort them at mount time to utilize this feature.

When using this feature with a single storage device, it has almost no
impact. However, for configurations where multiple storage devices are
mapped to the same dm device using F2FS, utilizing this feature can provide
some optimization benefits. Therefore, I believe it should not be limited
to just multi-devices usage.

00798cd24f f2fs: Add bggc_io_aware to adjust the priority of BG_GC when issuing IO
Currently, we have encountered some issues while testing ZUFS. In
situations near the storage limit (e.g., 50GB remaining), and after
simulating fragmentation by repeatedly writing and deleting data, we found
that application installation and startup tests conducted after idling for
a few minutes take significantly longer several times that of traditional
UFS. Tracing the operations revealed that the majority of I/Os were issued
by background GC, which blocks normal I/O operations.

Under normal circumstances, ZUFS indeed requires more background GC and
employs a more aggressive GC strategy. However, I aim to find a way to
minimize the impact on regular I/O operations under these near-limit
conditions. To address this, I have introduced a bggc_io_aware feature,
which controls the prioritization of background GC in the presence of I/Os.
This switch can be adjusted at the framework level to implement different
strategies. If set to AWARE_ALL_IO, all background GC operations will be
skipped during active I/O issuance. The default option remains consistent
with the current strategy, ensuring no change in behavior.

c3dd67681c cxl/region: Add inject and clear poison by region offset
Add CXL region debugfs attributes to inject and clear poison based
on an offset into the region. These new interfaces allow users to
operate on poison at the region level without needing to resolve
Device Physical Addresses (DPA) or target individual memdevs.

The implementation uses a new helper, region_offset_to_dpa_result()
that applies decoder interleave logic, including XOR-based address
decoding when applicable. Note that XOR decodes rely on driver
internal xormaps which are not exposed to userspace. So, this support
is not only a simplification of poison operations that could be done
using existing per memdev operations, but also it enables this
functionality for XOR interleaved regions for the first time.

New debugfs attributes are added in /sys/kernel/debug/cxl/regionX/:
inject_poison and clear_poison. These are only exposed if all memdevs
participating in the region support both inject and clear commands,
ensuring consistent and reliable behavior across multi-device regions.

If tracing is enabled, these operations are logged as cxl_poison
events in /sys/kernel/tracing/trace.

The ABI documentation warns users of the significant risks that
come with using these capabilities.

A CXL Maturity Map update shows this user flow is now supported.

beace86e61 Merge tag 'mm-stable-2025-07-30-15-25' of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm
Pull MM updates from Andrew Morton:
 "As usual, many cleanups. The below blurbiage describes 42 patchsets.
  21 of those are partially or fully cleanup work. "cleans up",
  "cleanup", "maintainability", "rationalizes", etc.

  I never knew the MM code was so dirty.

  "mm: ksm: prevent KSM from breaking merging of new VMAs" (Lorenzo Stoakes)
     addresses an issue with KSM's PR_SET_MEMORY_MERGE mode: newly
     mapped VMAs were not eligible for merging with existing adjacent
     VMAs.

  "mm/damon: introduce DAMON_STAT for simple and practical access monitoring" (SeongJae Park)
     adds a new kernel module which simplifies the setup and usage of
     DAMON in production environments.

  "stop passing a writeback_control to swap/shmem writeout" (Christoph Hellwig)
     is a cleanup to the writeback code which removes a couple of
     pointers from struct writeback_control.

  "drivers/base/node.c: optimization and cleanups" (Donet Tom)
     contains largely uncorrelated cleanups to the NUMA node setup and
     management code.

  "mm: userfaultfd: assorted fixes and cleanups" (Tal Zussman)
     does some maintenance work on the userfaultfd code.

  "Readahead tweaks for larger folios" (Ryan Roberts)
     implements some tuneups for pagecache readahead when it is reading
     into order>0 folios.

  "selftests/mm: Tweaks to the cow test" (Mark Brown)
     provides some cleanups and consistency improvements to the
     selftests code.

  "Optimize mremap() for large folios" (Dev Jain)
     does that. A 37% reduction in execution time was measured in a
     memset+mremap+munmap microbenchmark.

  "Remove zero_user()" (Matthew Wilcox)
     expunges zero_user() in favor of the more modern memzero_page().

  "mm/huge_memory: vmf_insert_folio_*() and vmf_insert_pfn_pud() fixes" (David Hildenbrand)
     addresses some warts which David noticed in the huge page code.
     These were not known to be causing any issues at this time.

  "mm/damon: use alloc_migrate_target() for DAMOS_MIGRATE_{HOT,COLD" (SeongJae Park)
     provides some cleanup and consolidation work in DAMON.

  "use vm_flags_t consistently" (Lorenzo Stoakes)
     uses vm_flags_t in places where we were inappropriately using other
     types.

  "mm/memfd: Reserve hugetlb folios before allocation" (Vivek Kasireddy)
     increases the reliability of large page allocation in the memfd
     code.

  "mm: Remove pXX_devmap page table bit and pfn_t type" (Alistair Popple)
     removes several now-unneeded PFN_* flags.

  "mm/damon: decouple sysfs from core" (SeongJae Park)
     implememnts some cleanup and maintainability work in the DAMON
     sysfs layer.

  "madvise cleanup" (Lorenzo Stoakes)
     does quite a lot of cleanup/maintenance work in the madvise() code.

  "madvise anon_name cleanups" (Vlastimil Babka)
     provides additional cleanups on top or Lorenzo's effort.

  "Implement numa node notifier" (Oscar Salvador)
     creates a standalone notifier for NUMA node memory state changes.
     Previously these were lumped under the more general memory
     on/offline notifier.

  "Make MIGRATE_ISOLATE a standalone bit" (Zi Yan)
     cleans up the pageblock isolation code and fixes a potential issue
     which doesn't seem to cause any problems in practice.

  "selftests/damon: add python and drgn based DAMON sysfs functionality tests" (SeongJae Park)
     adds additional drgn- and python-based DAMON selftests which are
     more comprehensive than the existing selftest suite.

  "Misc rework on hugetlb faulting path" (Oscar Salvador)
     fixes a rather obscure deadlock in the hugetlb fault code and
     follows that fix with a series of cleanups.

  "cma: factor out allocation logic from __cma_declare_contiguous_nid" (Mike Rapoport)
     rationalizes and cleans up the highmem-specific code in the CMA
     allocator.

  "mm/migration: rework movable_ops page migration (part 1)" (David Hildenbrand)
     provides cleanups and future-preparedness to the migration code.

  "mm/damon: add trace events for auto-tuned monitoring intervals and DAMOS quota" (SeongJae Park)
     adds some tracepoints to some DAMON auto-tuning code.

  "mm/damon: fix misc bugs in DAMON modules" (SeongJae Park)
     does that.

  "mm/damon: misc cleanups" (SeongJae Park)
     also does what it claims.

  "mm: folio_pte_batch() improvements" (David Hildenbrand)
     cleans up the large folio PTE batching code.

  "mm/damon/vaddr: Allow interleaving in migrate_{hot,cold} actions" (SeongJae Park)
     facilitates dynamic alteration of DAMON's inter-node allocation
     policy.

  "Remove unmap_and_put_page()" (Vishal Moola)
     provides a couple of page->folio conversions.

  "mm: per-node proactive reclaim" (Davidlohr Bueso)
     implements a per-node control of proactive reclaim - beyond the
     current memcg-based implementation.

  "mm/damon: remove damon_callback" (SeongJae Park)
     replaces the damon_callback interface with a more general and
     powerful damon_call()+damos_walk() interface.

  "mm/mremap: permit mremap() move of multiple VMAs" (Lorenzo Stoakes)
     implements a number of mremap cleanups (of course) in preparation
     for adding new mremap() functionality: newly permit the remapping
     of multiple VMAs when the user is specifying MREMAP_FIXED. It still
     excludes some specialized situations where this cannot be performed
     reliably.

  "drop hugetlb_free_pgd_range()" (Anthony Yznaga)
     switches some sparc hugetlb code over to the generic version and
     removes the thus-unneeded hugetlb_free_pgd_range().

  "mm/damon/sysfs: support periodic and automated stats update" (SeongJae Park)
     augments the present userspace-requested update of DAMON sysfs
     monitoring files. Automatic update is now provided, along with a
     tunable to control the update interval.

  "Some randome fixes and cleanups to swapfile" (Kemeng Shi)
     does what is claims.

  "mm: introduce snapshot_page" (Luiz Capitulino and David Hildenbrand)
     provides (and uses) a means by which debug-style functions can grab
     a copy of a pageframe and inspect it locklessly without tripping
     over the races inherent in operating on the live pageframe
     directly.

  "use per-vma locks for /proc/pid/maps reads" (Suren Baghdasaryan)
     addresses the large contention issues which can be triggered by
     reads from that procfs file. Latencies are reduced by more than
     half in some situations. The series also introduces several new
     selftests for the /proc/pid/maps interface.

  "__folio_split() clean up" (Zi Yan)
     cleans up __folio_split()!

  "Optimize mprotect() for large folios" (Dev Jain)
     provides some quite large (>3x) speedups to mprotect() when dealing
     with large folios.

  "selftests/mm: reuse FORCE_READ to replace "asm volatile("" : "+r" (XXX));" and some cleanup" (wang lian)
     does some cleanup work in the selftests code.

  "tools/testing: expand mremap testing" (Lorenzo Stoakes)
     extends the mremap() selftest in several ways, including adding
     more checking of Lorenzo's recently added "permit mremap() move of
     multiple VMAs" feature.

  "selftests/damon/sysfs.py: test all parameters" (SeongJae Park)
     extends the DAMON sysfs interface selftest so that it tests all
     possible user-requested parameters. Rather than the present minimal
     subset"
