mm/swap_cgroup: decouple swap cgroup recording and clearing
The current implementation of swap cgroup tracking is a bit complex and fragile: On charging path, swap_cgroup_record always records an actual memcg id, and it depends on the caller to make sure all entries passed in must belong to one single folio. As folios are always charged or uncharged as a whole, and always charged and uncharged in order, swap_cgroup doesn't need an extra lock. On uncharging path, swap_cgroup_record always sets the record to zero. These entries won't be charged again until uncharging is done. So there is no extra lock needed either. Worth noting that swap cgroup clearing may happen without folio involved, eg. exiting processes will zap its page table without swapin. The xchg/cmpxchg provides atomic operations and barriers to ensure no tearing or synchronization issue of these swap cgroup records. It works but quite error-prone. Things can be much clear and robust by decoupling recording and clearing into two helpers. Recording takes the actual folio being charged as argument, and clearing always set the record to zero, and refine the debug sanity checks to better reflect their usage Benchmark even showed a very slight improvement as it saved some extra arguments and lookups: make -j96 with defconfig on tmpfs in 1.5G memory cgroup using 4k folios: Before: sys 9617.23 (stdev 37.764062) After : sys 9541.54 (stdev 42.973976) make -j96 with defconfig on tmpfs in 2G memory cgroup using 64k folios: Before: sys 7358.98 (stdev 54.927593) After : sys 7337.82 (stdev 39.398956) Link: https://lkml.kernel.org/r/20241218114633.85196-5-ryncsn@gmail.com Signed-off-by: Kairui Song <kasong@tencent.com> Suggested-by: Chris Li <chrisl@kernel.org> Cc: Barry Song <baohua@kernel.org> Cc: Hugh Dickins <hughd@google.com> Cc: Johannes Weiner <hannes@cmpxchg.org> Cc: Michal Hocko <mhocko@kernel.org> Cc: Roman Gushchin <roman.gushchin@linux.dev> Cc: Shakeel Butt <shakeel.butt@linux.dev> Cc: Yosry Ahmed <yosryahmed@google.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> |

Pull MTD updates from Miquel Raynal:
"MTD changes:
- There's been no major core change, just a bunch of driver related
improvements.
Amongst them the conversion to of_property_present() for
non-boolean properties, the addition of the support for Fujitsu
MB85RS128TY FRAM, a couple of improvements to the phram driver and
the usual load of misc changes.
Raw NAND changes:
- A new controller driver, from Nuvoton, has been merged
- Bastien Curutchet has contributed a series improving the Davinci
controller driver, both on the organization of the code, but also
on the performance side. The binding has also been converted to
yaml, received a new OOB layout and now supports on-die ECC engines
- The Qualcomm controller driver has been deeply cleaned to extract
some parts of the code into a shared file with the Qualcomm SPI
memory controller
- Aside from these main changes, the Cadence binding has been
converted to yaml, the brcmnand controller driver has received a
small fix, otherwise some more minor changes have also made their
way in
SPI NAND changes:
- The SPI NAND subsystem has seen a great improvement, with the
advent of DTR operations (DDR operations, which may be extended to
the address cycles). The first vendor driver to benefit from these
improvements is the Winbond driver
- A new manufacturer driver is added SkyHigh, with a new constraint
for the core, it is impossible to disable the on-die ECC engine
- A Foresee device is also now supported
SPI NOR changes:
- Several flash entries have been added: Atmel AT25SF321, Spansion
S28HL256T and S28HL02GT
- Support for vcc-supply regulators and their DT bindings has been
added
- The mx25u25635f entry has been dropped. The flash shares its ID
with mx25u25645g and both parts have an SFDP table. Removing their
entry lets them be driven by the generic SFDP-based driver"

Pull pci updates from Bjorn Helgaas:
"Enumeration:
- Batch sizing of multiple BARs while memory decoding is disabled
instead of disabling/enabling decoding for each BAR individually;
this optimizes virtualized environments where toggling decoding
enable is expensive (Alex Williamson)
- Add host bridge .enable_device() and .disable_device() hooks for
bridges that need to configure things like Requester ID to StreamID
mapping when enabling devices (Frank Li)
- Extend struct pci_ecam_ops with .enable_device() and
.disable_device() hooks so drivers that use pci_host_common_probe()
instead of their own .probe() have a way to set the
.enable_device() callbacks (Marc Zyngier)
- Drop 'No bus range found' message so we don't complain when DTs
don't specify the default 'bus-range = <0x00 0xff>' (Bjorn Helgaas)
- Rename the drivers/pci/of_property.c struct of_pci_range to
of_pci_range_entry to avoid confusion with the global of_pci_range
in include/linux/of_address.h (Bjorn Helgaas)
Driver binding:
- Update resource request API documentation to encourage callers to
supply a driver name when requesting resources (Philipp Stanner)
- Export pci_intx_unmanaged() and pcim_intx() (always managed) so
callers of pci_intx() (which is sometimes managed) can explicitly
choose the one they need (Philipp Stanner)
- Convert drivers from pci_intx() to always-managed pcim_intx() or
never-managed pci_intx_unmanaged(): amd_sfh, ata (ahci, ata_piix,
pata_rdc, sata_sil24, sata_sis, sata_uli, sata_vsc), bnx2x, bna,
ntb, qtnfmac, rtsx, tifm_7xx1, vfio, xen-pciback (Philipp Stanner)
- Remove pci_intx_unmanaged() since pci_intx() is now always
unmanaged and pcim_intx() is always managed (Philipp Stanner)
Error handling:
- Unexport pcie_read_tlp_log() to encourage drivers to use PCI core
logging rather than building their own (Ilpo Järvinen)
- Move TLP Log handling to its own file (Ilpo Järvinen)
- Store number of supported End-End TLP Prefixes always so we can
read the correct number of DWORDs from the TLP Prefix Log (Ilpo
Järvinen)
- Read TLP Prefixes in addition to the Header Log in
pcie_read_tlp_log() (Ilpo Järvinen)
- Add pcie_print_tlp_log() to consolidate printing of TLP Header and
Prefix Log (Ilpo Järvinen)
- Quirk the Intel Raptor Lake-P PIO log size to accommodate vendor
BIOSes that don't configure it correctly (Takashi Iwai)
ASPM:
- Save parent L1 PM Substates config so when we restore it along with
an endpoint's config, the parent info isn't junk (Jian-Hong Pan)
Power management:
- Avoid D3 for Root Ports on TUXEDO Sirius Gen1 with old BIOS because
the system can't wake up from suspend (Werner Sembach)
Endpoint framework:
- Destroy the EPC device in devm_pci_epc_destroy(), which previously
didn't call devres_release() (Zijun Hu)
- Finish virtual EP removal in pci_epf_remove_vepf(), which
previously caused a subsequent pci_epf_add_vepf() to fail with
-EBUSY (Zijun Hu)
- Write BAR_MASK before iATU registers in pci_epc_set_bar() so we
don't depend on the BAR_MASK reset value being larger than the
requested BAR size (Niklas Cassel)
- Prevent changing BAR size/flags in pci_epc_set_bar() to prevent
reads from bypassing the iATU if we reduced the BAR size (Niklas
Cassel)
- Verify address alignment when programming iATU so we don't attempt
to write bits that are read-only because of the BAR size, which
could lead to directing accesses to the wrong address (Niklas
Cassel)
- Implement artpec6 pci_epc_features so we can rely on all drivers
supporting it so we can use it in EPC core code (Niklas Cassel)
- Check for BARs of fixed size to prevent endpoint drivers from
trying to change their size (Niklas Cassel)
- Verify that requested BAR size is a power of two when endpoint
driver sets the BAR (Niklas Cassel)
Endpoint framework tests:
- Clear pci-epf-test dma_chan_rx, not dma_chan_tx, after freeing
dma_chan_rx (Mohamed Khalfella)
- Correct the DMA MEMCPY test so it doesn't fail if the Endpoint
supports both DMA_PRIVATE and DMA_MEMCPY (Manivannan Sadhasivam)
- Add pci-epf-test and pci_endpoint_test support for capabilities
(Niklas Cassel)
- Add Endpoint test for consecutive BARs (Niklas Cassel)
- Remove redundant comparison from Endpoint BAR test because a > 1MB
BAR can always be exactly covered by iterating with a 1MB buffer
(Hans Zhang)
- Move and convert PCI Endpoint tests from tools/pci to Kselftests
(Manivannan Sadhasivam)
Apple PCIe controller driver:
- Convert StreamID mapping configuration from a bus notifier to the
.enable_device() and .disable_device() callbacks (Marc Zyngier)
Freescale i.MX6 PCIe controller driver:
- Add Requester ID to StreamID mapping configuration when enabling
devices (Frank Li)
- Use DWC core suspend/resume functions for imx6 (Frank Li)
- Add suspend/resume support for i.MX8MQ, i.MX8Q, and i.MX95 (Richard

i.MX8Q series (i.MX8QM, i.MX8QXP, and i.MX8DXL) Endpoints (Frank
Li)
- Add DT binding for optional i.MX95 Refclk and driver support to
enable it if the platform hasn't enabled it (Richard Zhu)
- Configure PHY based on controller being in Root Complex or Endpoint
mode (Frank Li)
- Rely on dbi2 and iATU base addresses from DT via
dw_pcie_get_resources() instead of hardcoding them (Richard Zhu)
- Deassert apps_reset in imx_pcie_deassert_core_reset() since it is
asserted in imx_pcie_assert_core_reset() (Richard Zhu)
- Add missing reference clock enable or disable logic for IMX6SX,
IMX7D, IMX8MM (Richard Zhu)
- Remove redundant imx7d_pcie_init_phy() since
imx7d_pcie_enable_ref_clk() does the same thing (Richard Zhu)
Freescale Layerscape PCIe controller driver:
- Simplify by using syscon_regmap_lookup_by_phandle_args() instead
of syscon_regmap_lookup_by_phandle() followed by
of_property_read_u32_array() (Krzysztof Kozlowski)
Marvell MVEBU PCIe controller driver:
- Add MODULE_DEVICE_TABLE() to enable module autoloading (Liao Chen)
MediaTek PCIe Gen3 controller driver:
- Use clk_bulk_prepare_enable() instead of separate
clk_bulk_prepare() and clk_bulk_enable() (Lorenzo Bianconi)
- Rearrange reset assert/deassert so they're both done in the
*_power_up() callbacks (Lorenzo Bianconi)
- Document that Airoha EN7581 requires PHY init and power-on before
PHY reset deassert, unlike other MediaTek Gen3 controllers (Lorenzo
Bianconi)
- Move Airoha EN7581 post-reset delay from the en7581 clock .enable()
method to mtk_pcie_en7581_power_up() (Lorenzo Bianconi)
- Sleep instead of delay during Airoha EN7581 power-up, since this is
a non-atomic context (Lorenzo Bianconi)
- Skip PERST# assertion on Airoha EN7581 during probe and
suspend/resume to avoid a hardware defect (Lorenzo Bianconi)
- Enable async probe to reduce system startup time (Douglas Anderson)
Microchip PolarFlare PCIe controller driver:
- Set up the inbound address translation based on whether the
platform allows coherent or non-coherent DMA (Daire McNamara)
- Update DT binding such that platforms are DMA-coherent by default
and must specify 'dma-noncoherent' if needed (Conor Dooley)
Mobiveil PCIe controller driver:
- Convert mobiveil-pcie.txt to YAML and update 'interrupt-names'
and 'reg-names' (Frank Li)
Qualcomm PCIe controller driver:
- Add DT SM8550 and SM8650 optional 'global' interrupt for link
events (Neil Armstrong)
- Add DT 'compatible' strings for IPQ5424 PCIe controller (Manikanta
Mylavarapu)
- If 'global' IRQ is supported for detection of Link Up events, tell
DWC core not to wait for link up (Krishna chaitanya chundru)
Renesas R-Car PCIe controller driver:
- Avoid passing stack buffer as resource name (King Dix)
Rockchip PCIe controller driver:
- Simplify clock and reset handling by using bulk interfaces (Anand
Moon)
- Pass typed rockchip_pcie (not void) pointer to
rockchip_pcie_disable_clocks() (Anand Moon)
- Return -ENOMEM, not success, when pci_epc_mem_alloc_addr() fails
(Dan Carpenter)
Rockchip DesignWare PCIe controller driver:
- Use dll_link_up IRQ to detect Link Up and enumerate devices so
users don't have to manually rescan (Niklas Cassel)
- Tell DWC core not to wait for link up since the 'sys' interrupt is
required and detects Link Up events (Niklas Cassel)
Synopsys DesignWare PCIe controller driver:
- Don't wait for link up in DWC core if driver can detect Link Up
event (Krishna chaitanya chundru)
- Update ICC and OPP votes after Link Up events (Krishna chaitanya
chundru)
- Always stop link in dw_pcie_suspend_noirq(), which is required at
least for i.MX8QM to re-establish link on resume (Richard Zhu)
- Drop racy and unnecessary LTSSM state check before sending
PME_TURN_OFF message in dw_pcie_suspend_noirq() (Richard Zhu)
- Add struct of_pci_range.parent_bus_addr for devices that need their
immediate parent bus address, not the CPU address, e.g., to program
an internal Address Translation Unit (iATU) (Frank Li)
TI DRA7xx PCIe controller driver:
- Simplify by using syscon_regmap_lookup_by_phandle_args() instead of
syscon_regmap_lookup_by_phandle() followed by
of_parse_phandle_with_fixed_args() or of_property_read_u32_index()
(Krzysztof Kozlowski)
Xilinx Versal CPM PCIe controller driver:
- Add DT binding and driver support for Xilinx Versal CPM5
(Thippeswamy Havalige)
MicroSemi Switchtec management driver:
- Add Microchip PCI100X device IDs (Rakesh Babu Saladi)
Miscellaneous:
- Move reset related sysfs code from pci.c to pci-sysfs.c where other
similar code lives (Ilpo Järvinen)
- Simplify reset_method_store() memory management by using __free()
instead of explicit kfree() cleanup (Ilpo Järvinen)
- Constify struct bin_attribute for sysfs, VPD, P2PDMA, and the IBM
ACPI hotplug driver (Thomas Weißschuh)
- Remove redundant PCI_VSEC_HDR and PCI_VSEC_HDR_LEN_SHIFT (Dongdong

Pull kvm updates from Paolo Bonzini:
"Loongarch:
- Clear LLBCTL if secondary mmu mapping changes
- Add hypercall service support for usermode VMM
x86:
- Add a comment to kvm_mmu_do_page_fault() to explain why KVM
performs a direct call to kvm_tdp_page_fault() when RETPOLINE is
enabled
- Ensure that all SEV code is compiled out when disabled in Kconfig,
even if building with less brilliant compilers
- Remove a redundant TLB flush on AMD processors when guest CR4.PGE
changes
- Use str_enabled_disabled() to replace open coded strings
- Drop kvm_x86_ops.hwapic_irr_update() as KVM updates hardware's
APICv cache prior to every VM-Enter
- Overhaul KVM's CPUID feature infrastructure to track all vCPU
capabilities instead of just those where KVM needs to manage state
and/or explicitly enable the feature in hardware. Along the way,
refactor the code to make it easier to add features, and to make it
more self-documenting how KVM is handling each feature
- Rework KVM's handling of VM-Exits during event vectoring; this
plugs holes where KVM unintentionally puts the vCPU into infinite
loops in some scenarios (e.g. if emulation is triggered by the
exit), and brings parity between VMX and SVM
- Add pending request and interrupt injection information to the
kvm_exit and kvm_entry tracepoints respectively
- Fix a relatively benign flaw where KVM would end up redoing RDPKRU
when loading guest/host PKRU, due to a refactoring of the kernel
helpers that didn't account for KVM's pre-checking of the need to
do WRPKRU
- Make the completion of hypercalls go through the complete_hypercall
function pointer argument, no matter if the hypercall exits to
userspace or not.
Previously, the code assumed that KVM_HC_MAP_GPA_RANGE specifically
went to userspace, and all the others did not; the new code need
not special case KVM_HC_MAP_GPA_RANGE and in fact does not care at
all whether there was an exit to userspace or not
- As part of enabling TDX virtual machines, support support
separation of private/shared EPT into separate roots.
When TDX will be enabled, operations on private pages will need to
go through the privileged TDX Module via SEAMCALLs; as a result,
they are limited and relatively slow compared to reading a PTE.
The patches included in 6.14 allow KVM to keep a mirror of the
private EPT in host memory, and define entries in kvm_x86_ops to
operate on external page tables such as the TDX private EPT
- The recently introduced conversion of the NX-page reclamation
kthread to vhost_task moved the task under the main process. The
task is created as soon as KVM_CREATE_VM was invoked and this, of
course, broke userspace that didn't expect to see any child task of
the VM process until it started creating its own userspace threads.
In particular crosvm refuses to fork() if procfs shows any child
task, so unbreak it by creating the task lazily. This is arguably a
userspace bug, as there can be other kinds of legitimate worker
tasks and they wouldn't impede fork(); but it's not like userspace
has a way to distinguish kernel worker tasks right now. Should they
show as "Kthread: 1" in proc/.../status?
x86 - Intel:
- Fix a bug where KVM updates hardware's APICv cache of the highest
ISR bit while L2 is active, while ultimately results in a
hardware-accelerated L1 EOI effectively being lost
- Honor event priority when emulating Posted Interrupt delivery
during nested VM-Enter by queueing KVM_REQ_EVENT instead of
immediately handling the interrupt
- Rework KVM's processing of the Page-Modification Logging buffer to
reap entries in the same order they were created, i.e. to mark gfns
dirty in the same order that hardware marked the page/PTE dirty
- Misc cleanups
Generic:
- Cleanup and harden kvm_set_memory_region(); add proper lockdep
assertions when setting memory regions and add a dedicated API for
setting KVM-internal memory regions. The API can then explicitly
disallow all flags for KVM-internal memory regions
- Explicitly verify the target vCPU is online in kvm_get_vcpu() to
fix a bug where KVM would return a pointer to a vCPU prior to it
being fully online, and give kvm_for_each_vcpu() similar treatment
to fix a similar flaw
- Wait for a vCPU to come online prior to executing a vCPU ioctl, to
fix a bug where userspace could coerce KVM into handling the ioctl
on a vCPU that isn't yet onlined
- Gracefully handle xarray insertion failures; even though such
failures are impossible in practice after xa_reserve(), reserving
an entry is always followed by xa_store() which does not know (or
differentiate) whether there was an xa_reserve() before or not
RISC-V:
- Zabha, Svvptc, and Ziccrse extension support for guests. None of
them require anything in KVM except for detecting them and marking
them as supported; Zabha adds byte and halfword atomic operations,
while the others are markers for specific operation of the TLB and
of LL/SC instructions respectively
- Virtualize SBI system suspend extension for Guest/VM
- Support firmware counters which can be used by the guests to
collect statistics about traps that occur in the host
Selftests:
- Rework vcpu_get_reg() to return a value instead of using an
out-param, and update all affected arch code accordingly
- Convert the max_guest_memory_test into a more generic
mmu_stress_test. The basic gist of the "conversion" is to have the
test do mprotect() on guest memory while vCPUs are accessing said
memory, e.g. to verify KVM and mmu_notifiers are working as
intended
- Play nice with treewrite builds of unsupported architectures, e.g.
arm (32-bit), as KVM selftests' Makefile doesn't do anything to
ensure the target architecture is actually one KVM selftests
supports
- Use the kernel's $(ARCH) definition instead of the target triple
for arch specific directories, e.g. arm64 instead of aarch64,
mainly so as not to be different from the rest of the kernel
- Ensure that format strings for logging statements are checked by
the compiler even when the logging statement itself is disabled
- Attempt to whack the last LLC references/misses mole in the Intel
PMU counters test by adding a data load and doing CLFLUSH{OPT} on
the data instead of the code being executed. It seems that modern
Intel CPUs have learned new code prefetching tricks that bypass the
PMU counters
- Fix a flaw in the Intel PMU counters test where it asserts that
events are counting correctly without actually knowing what the
events count given the underlying hardware; this can happen if
Intel reuses a formerly microarchitecture-specific event encoding
as an architectural event, as was the case for Top-Down Slots"

include/linux/lz4.h: add some missing macros
Currently, LZ4_DISTANCE_MAX and LZ4_DECOMPRESS_INPLACE_MARGIN are defined in the erofs subsystem for LZ4 in-place decompression, which is somewhat unsuitable since they should belong to the LZ4 itself and may change with future LZ4 codebase updates. Move them to include/linux/lz4.h to match the upstream LZ4 library [1]. No logic changes.

minmax.h: remove some #defines that are only expanded once
The bodies of __signed_type_use() and __unsigned_type_use() are much the same size as their names - so put the bodies in the only line that expands them. Similarly __signed_type() is defined separately for 64bit and then used exactly once just below. Change the test for __signed_type from CONFIG_64BIT to one based on gcc defined macros so that the code is valid if it gets used outside of a kernel build.

minmax.h: simplify the variants of clamp()
Always pass a 'type' through to __clamp_once(), pass '__auto_type' from clamp() itself.

minmax.h: reduce the #define expansion of min(), max() and clamp()
Since the test for signed values being non-negative only relies on __builtion_constant_p() (not is_constexpr()) it can use the 'ux' variable instead of the caller supplied expression. This means that the #define parameters are only expanded twice. Once in the code and once quoted in the error message.

kvm: defer huge page recovery vhost task to later
Some libraries want to ensure they are single threaded before forking,
so making the kernel's kvm huge page recovery process a vhost task of
the user process breaks those. The minijail library used by crosvm is
one such affected application.
Defer the task to after the first VM_RUN call, which occurs after the
parent process has forked all its jailed processes. This needs to happen
only once for the kvm instance, so introduce some general-purpose
infrastructure for that, too. It's similar in concept to pthread_once;
except it is actually usable, because the callback takes a parameter.

Merge tag 'trace-v6.14-3' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace
Pull tracing updates from Steven Rostedt: - Cleanup with guard() and free() helpers There were several places in the code that had a lot of "goto out" in the error paths to either unlock a lock or free some memory that was allocated. But this is error prone. Convert the code over to use the guard() and free() helpers that let the compiler unlock locks or free memory when the function exits. - Update the Rust tracepoint code to use the C code too There was some duplication of the tracepoint code for Rust that did the same logic as the C code. Add a helper that makes it possible for both algorithms to use the same logic in one place. - Add poll to trace event hist files It is useful to know when an event is triggered, or even with some filtering. Since hist files of events get updated when active and the event is triggered, allow applications to poll the hist file and wake up when an event is triggered. This will let the application know that the event it is waiting for happened. - Add :mod: command to enable events for current or future modules The function tracer already has a way to enable functions to be traced in modules by writing ":mod:<module>" into set_ftrace_filter. That will enable either all the functions for the module if it is loaded, or if it is not, it will cache that command, and when the module is loaded that matches <module>, its functions will be enabled. This also allows init functions to be traced. But currently events do not have that feature. Add the command where if ':mod:<module>' is written into set_event, then either all the modules events are enabled if it is loaded, or cache it so that the module's events are enabled when it is loaded. This also works from the kernel command line, where "trace_event=:mod:<module>", when the module is loaded at boot up, its events will be enabled then. * tag 'trace-v6.14-3' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: (26 commits) tracing: Fix output of set_event for some cached module events tracing: Fix allocation of printing set_event file content tracing: Rename update_cache() to update_mod_cache() tracing: Fix #if CONFIG_MODULES to #ifdef CONFIG_MODULES selftests/ftrace: Add test that tests event :mod: commands tracing: Cache ":mod:" events for modules not loaded yet tracing: Add :mod: command to enabled module events selftests/tracing: Add hist poll() support test tracing/hist: Support POLLPRI event for poll on histogram tracing/hist: Add poll(POLLIN) support on hist file tracing: Fix using ret variable in tracing_set_tracer() tracepoint: Reduce duplication of __DO_TRACE_CALL tracing/string: Create and use __free(argv_free) in trace_dynevent.c tracing: Switch trace_stat.c code over to use guard() tracing: Switch trace_stack.c code over to use guard() tracing: Switch trace_osnoise.c code over to use guard() and __free() tracing: Switch trace_events_synth.c code over to use guard() tracing: Switch trace_events_filter.c code over to use guard() tracing: Switch trace_events_trigger.c code over to use guard() tracing: Switch trace_events_hist.c code over to use guard() ... |

Merge tag 'fsnotify_hsm_for_v6.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-fs
Pull fsnotify pre-content notification support from Jan Kara: "This introduces a new fsnotify event (FS_PRE_ACCESS) that gets generated before a file contents is accessed. The event is synchronous so if there is listener for this event, the kernel waits for reply. On success the execution continues as usual, on failure we propagate the error to userspace. This allows userspace to fill in file content on demand from slow storage. The context in which the events are generated has been picked so that we don't hold any locks and thus there's no risk of a deadlock for the userspace handler. The new pre-content event is available only for users with global CAP_SYS_ADMIN capability (similarly to other parts of fanotify functionality) and it is an administrator responsibility to make sure the userspace event handler doesn't do stupid stuff that can DoS the system. Based on your feedback from the last submission, fsnotify code has been improved and now file->f_mode encodes whether pre-content event needs to be generated for the file so the fast path when nobody wants pre-content event for the file just grows the additional file->f_mode check. As a bonus this also removes the checks whether the old FS_ACCESS event needs to be generated from the fast path. Also the place where the event is generated during page fault has been moved so now filemap_fault() generates the event if and only if there is no uptodate folio in the page cache. Also we have dropped FS_PRE_MODIFY event as current real-world users of the pre-content functionality don't really use it so let's start with the minimal useful feature set" * tag 'fsnotify_hsm_for_v6.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-fs: (21 commits) fanotify: Fix crash in fanotify_init(2) fs: don't block write during exec on pre-content watched files fs: enable pre-content events on supported file systems ext4: add pre-content fsnotify hook for DAX faults btrfs: disable defrag on pre-content watched files xfs: add pre-content fsnotify hook for DAX faults fsnotify: generate pre-content permission event on page fault mm: don't allow huge faults for files with pre content watches fanotify: disable readahead if we have pre-content watches fanotify: allow to set errno in FAN_DENY permission response fanotify: report file range info with pre-content events fanotify: introduce FAN_PRE_ACCESS permission event fsnotify: generate pre-content permission event on truncate fsnotify: pass optional file access range in pre-content event fsnotify: introduce pre-content permission events fanotify: reserve event bit of deprecated FAN_DIR_MODIFY fanotify: rename a misnamed constant fanotify: don't skip extra event info if no info_mode is set fsnotify: check if file is actually being watched for pre-content events on open fsnotify: opt-in for permission events at file open time ... |

hrtimers: Force migrate away hrtimers queued after CPUHP_AP_HRTIMERS_DYING
hrtimers are migrated away from the dying CPU to any online target at the CPUHP_AP_HRTIMERS_DYING stage in order not to delay bandwidth timers handling tasks involved in the CPU hotplug forward progress. However wakeups can still be performed by the outgoing CPU after CPUHP_AP_HRTIMERS_DYING. Those can result again in bandwidth timers being armed. Depending on several considerations (crystal ball power management based election, earliest timer already enqueued, timer migration enabled or not), the target may eventually be the current CPU even if offline. If that happens, the timer is eventually ignored. The most notable example is RCU which had to deal with each and every of those wake-ups by deferring them to an online CPU, along with related workarounds: _ |

io_uring: get rid of alloc cache init_once handling
init_once is called when an object doesn't come from the cache, and hence needs initial clearing of certain members. While the whole struct could get cleared by memset() in that case, a few of the cache members are large enough that this may cause unnecessary overhead if the caches used aren't large enough to satisfy the workload. For those cases, some churn of kmalloc+kfree is to be expected. Ensure that the 3 users that need clearing put the members they need cleared at the start of the struct, and wrap the rest of the struct in a struct group so the offset is known. While at it, improve the interaction with KASAN such that when/if KASAN writes to members inside the struct that should be retained over caching, it won't trip over itself. For rw and net, the retaining of the iovec over caching is disabled if KASAN is enabled. A helper will free and clear those members in that case. Signed-off-by: Jens Axboe <axboe@kernel.dk> |

Pull bpf updates from Alexei Starovoitov:
"A smaller than usual release cycle.
The main changes are:
- Prepare selftest to run with GCC-BPF backend (Ihor Solodrai)
In addition to LLVM-BPF runs the BPF CI now runs GCC-BPF in compile
only mode. Half of the tests are failing, since support for
btf_decl_tag is still WIP, but this is a great milestone.
- Convert various samples/bpf to selftests/bpf/test_progs format
(Alexis Lothoré and Bastien Curutchet)
- Teach verifier to recognize that array lookup with constant
in-range index will always succeed (Daniel Xu)
- Cleanup migrate disable scope in BPF maps (Hou Tao)
- Fix bpf_timer destroy path in PREEMPT_RT (Hou Tao)
- Always use bpf_mem_alloc in bpf_local_storage in PREEMPT_RT (Martin
KaFai Lau)
- Refactor verifier lock support (Kumar Kartikeya Dwivedi)
This is a prerequisite for upcoming resilient spin lock.
- Remove excessive 'may_goto +0' instructions in the verifier that
LLVM leaves when unrolls the loops (Yonghong Song)
- Remove unhelpful bpf_probe_write_user() warning message (Marco
Elver)
- Add fd_array_cnt attribute for prog_load command (Anton Protopopov)
This is a prerequisite for upcoming support for static_branch"

Pull CRC updates from Eric Biggers: - Reorganize the architecture-optimized CRC32 and CRC-T10DIF code to be directly accessible via the library API, instead of requiring the crypto API. This is much simpler and more efficient. - Convert some users such as ext4 to use the CRC32 library API instead of the crypto API. More conversions like this will come later. - Add a KUnit test that tests and benchmarks multiple CRC variants. Remove older, less-comprehensive tests that are made redundant by this. - Add an entry to MAINTAINERS for the kernel's CRC library code. I'm volunteering to maintain it.

Merge tag 'acpi-6.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull ACPI updates from Rafael Wysocki:
"The most significant change here is replacing msleep() in
acpi_os_sleep() with usleep_range() to reduce spurious sleep time due
to timer inaccuracy which may spectacularly reduce the duration of
system suspend and resume transitions on some systems.
All of the other changes fall into the fixes and cleanups category
this time.
Specifics:
- Use usleep_range() instead of msleep() in acpi_os_sleep() to reduce
excessive delays due to timer inaccuracy, mostly affecting system
suspend and resume (Rafael Wysocki)
- Use str_enabled_disabled() string helpers in the ACPI tables
parsing code to make it easier to follow (Sunil V L)
- Update device properties parsing on systems using ACPI so that data
firmware nodes resulting from _DSD evaluation are treated as
available in firmware nodes walks (Sakari Ailus)
- Fix missing guid_t declaration in linux/prmt.h (Robert Richter)
- Update the GHES handling code to follow the global panic= policy
instead of overriding it by force-rebooting the system after a
fatal HW error has been reported (Borislav Petkov)
- Update messages printed by the ACPI battery driver to always refer
to driver extensions as "hooks" to avoid confusion with similar
functionality in the power supply subsystem in the future (Thomas
Weißschuh)
- Fix .probe() error path cleanup in the ACPI fan driver to avoid
memory leaks (Joe Hattori)
- Constify 'struct bin_attribute' in some places in the ACPI
subsystem and mark it as __ro_after_init in one place to prevent
binary blob attributes from being updated (Thomas Weißschuh)
- Add empty stubs for several ACPI-related symbols so that they can
be used when CONFIG_ACPI is unset and use them for removing
unnecessary conditional compilation from the ipu-bridge driver
(Ricardo Ribalda)"

"The majority of changes here are cpufreq updates which are dominated
by amd-pstate driver changes, like in the previous cycle. Moreover,
changes related to amd-pstate are also the majority of cpupower
utility updates.
Included are some pieces of new hardware support, like the addition of
Clearwater Forest processors support to intel_idle, new cpufreq driver
for Airoha SoCs, and Apple cpufreq driver extensions to support more
SoCs. The intel_pstate driver is also extended to be able to support
new platforms by using ACPI CPPC to compute scaling factors between
HWP performance states and frequency.
The rest is mostly fixes and cleanups in assorted pieces of power
management code.
Specifics:
- Use str_enable_disable()-like helpers in cpufreq (Krzysztof
Kozlowski)
- Extend the Apple cpufreq driver to support more SoCs (Hector
Martin, Nick Chan)

not being used (Mario Limonciello)
- Fix a precision issue with frequency calculation in the amd-pstate
driver (Naresh Solanki)
- Add ftrace event to the amd-pstate driver for active mode (Mario
Limonciello)
- Set default EPP policy on Ryzen processors in amd-pstate (Mario
Limonciello)
- Clean up the amd-pstate cpufreq driver and optimize it to increase
code reuse (Mario Limonciello, Dhananjay Ugwekar)
- Use CPPC to get scaling factors between HWP performance levels and
frequency in the intel_pstate driver and make it stop using a
built-in scaling factor for Arrow Lake processors (Rafael Wysocki)
- Make intel_pstate initialize epp_policy to CPUFREQ_POLICY_UNKNOWN
for consistency with CPU offline (Christian Loehle)
- Fix superfluous updates caused by need_freq_update in the schedutil
cpufreq governor (Sultan Alsawaf)
- Allow configuring the system suspend-resume (DPM) watchdog to warn
earlier than panic (Douglas Anderson)
- Implement devm_device_init_wakeup() helper and introduce a device-
managed variant of dev_pm_set_wake_irq() (Joe Hattori, Peng Fan)
- Remove direct inclusions of 'pm_wakeup.h' which should be only
included via 'device.h' (Wolfram Sang)
- Clean up two comments in the core system-wide PM code (Rafael
Wysocki, Randy Dunlap)
- Add Clearwater Forest processor support to the intel_idle cpuidle
driver (Artem Bityutskiy)
- Clean up the Exynos devfreq driver and devfreq core (Markus
Elfring, Jeongjun Park)

header changes for cpufreq.h to SWIG bindings in cpupower (John B.
Wyatt IV)
- Add missing residency header changes in cpuidle.h to SWIG bindings
in cpupower (John B. Wyatt IV)
- Add output files to .gitignore and clean them up in "make clean" in
selftests/cpufreq (Li Zhijian)
- Fix cross-compilation in cpupower Makefile (Peng Fan)
- Revise the is_valid flag handling for idle_monitor in the cpupower
utility (wangfushuai)
- Extend and clean up AMD processors support in cpupower (Mario
Limonciello)"
