Pull SoC DT updates from Arnd Bergmann:
"There is one new SoC for each 32-bit Arm and 64-bit RISC-V, but both
the Rockchips rv1109 and Sopgho CV1812H are just minor variations of
already supported chips.
The other six new SoCs are all part of existing arm64 families, but
are somewhat more interesting:
- Samsung ExynosAutov920 is an automotive chip, and the first one we
support based on the Cortex-A78AE core with lockstep mode.
- Google gs101 (Tensor G1) is the chip used in a number of Pixel
phones, and is grouped with Samsung Exynos here since it is based
on the same SoC design, sharing most of its IP blocks with that
series.
- MediaTek MT8188 is a new chip used for mid-range tablets and
Chromebooks, using two Cortex-A78 cores where the older MT8195 had
four of them.
- Qualcomm SM8650 (Snapdragon 8 Gen 3) is their current top range
phone SoC and the first supported chip based on Cortex-X4,
Cortex-A720 and Cortex-A520.
- Qualcomm X1E80100 (Snapdragon X Elite) in turn is the latest Laptop
chip using the custom Oryon cores.
- Unisoc UMS9620 (Tanggula 7 series) is a 5G phone SoC based on
Cortex-A76 and Cortex-A55
In terms of boards, we have
- Five old Microsoft Lumia phones, the HTC One Mini 2, Motorola Moto
G 4G, and Huawei Honor 5X/GR5, all based on Snapdragon SoCs.
- Multiple Rockchips mobile gaming systems (Anbernic RG351V, Powkiddy
RK2023, Powkiddy X55) along with the Sonoff iHost Smart Home Hub
and a few Rockchips SBCs
- Some ComXpress boards based on Marvell CN913x, which is the
follow-up to Armada 7xxx/8xxx.
- Six new industrial/embedded boards based on NXP i.MX8 and i.MX9
- Mediatek MT8183 based Chromebooks from Lenovo, Asus and Acer.
- Toradex Verdin AM62 Mallow carrier for TI AM62
- Huashan Pi board based on the SophGo CV1812H RISC-V chip
- Two boards based on Allwinner H616/H618
- A number of reference boards for various added SoCs from Qualcomm,
Mediatek, Google, Samsung, NXP and Spreadtrum
As usual, there are cleanups and warning fixes across all platforms as
well as added features for several of them"

Merge tag 'net-next-6.8' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next
Pull networking updates from Paolo Abeni:
"The most interesting thing is probably the networking structs
reorganization and a significant amount of changes is around
self-tests.
Core & protocols:
- Analyze and reorganize core networking structs (socks, netdev,
netns, mibs) to optimize cacheline consumption and set up build
time warnings to safeguard against future header changes
This improves TCP performances with many concurrent connections up
to 40%
- Add page-pool netlink-based introspection, exposing the memory
usage and recycling stats. This helps indentify bad PP users and
possible leaks
- Refine TCP/DCCP source port selection to no longer favor even
source port at connect() time when IP_LOCAL_PORT_RANGE is set. This
lowers the time taken by connect() for hosts having many active
connections to the same destination
- Refactor the TCP bind conflict code, shrinking related socket
structs
- Refactor TCP SYN-Cookie handling, as a preparation step to allow
arbitrary SYN-Cookie processing via eBPF
- Tune optmem_max for 0-copy usage, increasing the default value to
128KB and namespecifying it
- Allow coalescing for cloned skbs coming from page pools, improving
RX performances with some common configurations
- Reduce extension header parsing overhead at GRO time
- Add bridge MDB bulk deletion support, allowing user-space to
request the deletion of matching entries
- Reorder nftables struct members, to keep data accessed by the
datapath first
- Introduce TC block ports tracking and use. This allows supporting
multicast-like behavior at the TC layer
- Remove UAPI support for retired TC qdiscs (dsmark, CBQ and ATM) and
classifiers (RSVP and tcindex)
- More data-race annotations
- Extend the diag interface to dump TCP bound-only sockets
- Conditional notification of events for TC qdisc class and actions
- Support for WPAN dynamic associations with nearby devices, to form
a sub-network using a specific PAN ID
- Implement SMCv2.1 virtual ISM device support
- Add support for Batman-avd mulicast packet type
BPF:
- Tons of verifier improvements:
- BPF register bounds logic and range support along with a large
test suite
- log improvements
- complete precision tracking support for register spills
- track aligned STACK_ZERO cases as imprecise spilled registers.
This improves the verifier "instructions processed" metric from
single digit to 50-60% for some programs
- support for user's global BPF subprogram arguments with few
commonly requested annotations for a better developer
experience
- support tracking of BPF_JNE which helps cases when the compiler
transforms (unsigned) "a > 0" into "if a == 0 goto xxx" and the
like
- several fixes
- Add initial TX metadata implementation for AF_XDP with support in
mlx5 and stmmac drivers. Two types of offloads are supported right
now, that is, TX timestamp and TX checksum offload
- Fix kCFI bugs in BPF all forms of indirect calls from BPF into
kernel and from kernel into BPF work with CFI enabled. This allows
BPF to work with CONFIG_FINEIBT=y
- Change BPF verifier logic to validate global subprograms lazily
instead of unconditionally before the main program, so they can be
guarded using BPF CO-RE techniques
- Support uid/gid options when mounting bpffs
- Add a new kfunc which acquires the associated cgroup of a task
within a specific cgroup v1 hierarchy where the latter is
identified by its id
- Extend verifier to allow bpf_refcount_acquire() of a map value
field obtained via direct load which is a use-case needed in
sched_ext
- Add BPF link_info support for uprobe multi link along with bpftool
integration for the latter
- Support for VLAN tag in XDP hints
- Remove deprecated bpfilter kernel leftovers given the project is
developed in user-space (https://github.com/facebook/bpfilter)
Misc:
- Support for parellel TC self-tests execution
- Increase MPTCP self-tests coverage
- Updated the bridge documentation, including several so-far
undocumented features
- Convert all the net self-tests to run in unique netns, to avoid
random failures due to conflict and allow concurrent runs
- Add TCP-AO self-tests
- Add kunit tests for both cfg80211 and mac80211
- Autogenerate Netlink families documentation from YAML spec
- Add yml-gen support for fixed headers and recursive nests, the tool
can now generate user-space code for all genetlink families for
which we have specs
- A bunch of additional module descriptions fixes
- Catch incorrect freeing of pages belonging to a page pool
Driver API:
- Rust abstractions for network PHY drivers; do not cover yet the
full C API, but already allow implementing functional PHY drivers
in rust
- Introduce queue and NAPI support in the netdev Netlink interface,
allowing complete access to the device <> NAPIs <> queues
relationship
- Introduce notifications filtering for devlink to allow control
application scale to thousands of instances
- Improve PHY validation, requesting rate matching information for
each ethtool link mode supported by both the PHY and host
- Add support for ethtool symmetric-xor RSS hash
- ACPI based Wifi band RFI (WBRF) mitigation feature for the AMD
platform
- Expose pin fractional frequency offset value over new DPLL generic
netlink attribute
- Convert older drivers to platform remove callback returning void
- Add support for PHY package MMD read/write

Merge tag 'sysctl-6.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/mcgrof/linux
Pull sysctl updates from Luis Chamberlain:
"To help make the move of sysctls out of kernel/sysctl.c not incur a
size penalty sysctl has been changed to allow us to not require the
sentinel, the final empty element on the sysctl array. Joel Granados
has been doing all this work.
In the v6.6 kernel we got the major infrastructure changes required to
support this. For v6.7 we had all arch/ and drivers/ modified to
remove the sentinel. For v6.8-rc1 we get a few more updates for fs/
directory only.
The kernel/ directory is left but we'll save that for v6.9-rc1 as
those patches are still being reviewed. After that we then can expect
also the removal of the no longer needed check for procname == NULL.
Let us recap the purpose of this work:
- this helps reduce the overall build time size of the kernel and run
time memory consumed by the kernel by about ~64 bytes per array
- the extra 64-byte penalty is no longer inncurred now when we move
sysctls out from kernel/sysctl.c to their own files
Thomas Weißschuh also sent a few cleanups, for v6.9-rc1 we expect to
see further work by Thomas Weißschuh with the constificatin of the
struct ctl_table.
Due to Joel Granados's work, and to help bring in new blood, I have
suggested for him to become a maintainer and he's accepted. So for
v6.9-rc1 I look forward to seeing him sent you a pull request for
further sysctl changes. This also removes Iurii Zaikin as a maintainer
as he has moved on to other projects and has had no time to help at
all"

Merge tag 'afs-fix-rotation-20240105' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs
Pull afs updates from David Howells:
"The majority of the patches are aimed at fixing and improving the AFS
filesystem's rotation over server IP addresses, but there are also
some fixes from Oleg Nesterov for the use of read_seqbegin_or_lock().
- Fix fileserver probe handling so that the next round of probes
doesn't break ongoing server/address rotation by clearing all the
probe result tracking. This could occasionally cause the rotation
algorithm to drop straight through, give a 'successful' result
without actually emitting any RPC calls, leaving the reply buffer
in an undefined state.
Instead, detach the probe results into a separate struct and
allocate a new one each time we start probing and update the
pointer to it. Probes are also sent in order of address preference
to try and improve the chance that the preferred one will complete
first.
- Fix server rotation so that it uses configurable address
preferences across on the probes that have completed so far than
ranking them by RTT as the latter doesn't necessarily give the best
route. The preference list can be altered by writing into
/proc/net/afs/addr_prefs.
- Fix the handling of Read-Only (and Backup) volume callbacks as
there is one per volume, not one per file, so if someone performs a
command that, say, offlines the volume but doesn't change it, when
it comes back online we don't spam the server with a status fetch
for every vnode we're using. Instead, check the Creation timestamp
in the VolSync record when prompted by a callback break.
- Handle volume regression (ie. a RW volume being restored from a
backup) by scrubbing all cache data for that volume. This is
detected from the VolSync creation timestamp.
- Adjust abort handling and abort -> error mapping to match better
with what other AFS clients do.
- Fix offline and busy volume state handling as they only apply to
individual server instances and not entire volumes and the rotation
algorithm should go and look at other servers if available. Also
make it sleep briefly before each retry if all the volume instances
are unavailable"

Pull btrfs updates from David Sterba:
"There are no exciting changes for users, it's been mostly API
conversions and some fixes or refactoring.
The mount API conversion is a base for future improvements that would
come with VFS. Metadata processing has been converted to folios, not
yet enabling the large folios but it's one patch away once everything
gets tested enough.
Core changes:
- convert extent buffers to folios:
- direct API conversion where possible
- performance can drop by a few percent on metadata heavy
workloads, the folio sizes are not constant and the calculations
add up in the item helpers
- both regular and subpage modes
- data cannot be converted yet, we need to port that to iomap and
there are some other generic changes required
- convert mount to the new API, should not be user visible:
- options deprecated long time ago have been removed: inode_cache,
recovery
- the new logic that splits mount to two phases slightly changes
timing of device scanning for multi-device filesystems
- LSM options will now work (like for selinux)
- convert delayed nodes radix tree to xarray, preserving the
preload-like logic that still allows to allocate with GFP_NOFS
- more validation of sysfs value of scrub_speed_max
- refactor chunk map structure, reduce size and improve performance
- extent map refactoring, smaller data structures, improved
performance
- reduce size of struct extent_io_tree, embedded in several
structures
- temporary pages used for compression are cached and attached to a
shrinker, this may slightly improve performance
- in zoned mode, remove redirty extent buffer tracking, zeros are
written in case an out-of-order is detected and proper data are
written to the actual write pointer
- cleanups, refactoring, error message improvements, updated tests
- verify and update branch name or tag
- remove unwanted text"

Pull power management updates from Rafael Wysocki:
"These add support for new processors (Sierra Forest, Grand Ridge and
Meteor Lake) to the intel_idle driver, make intel_pstate run on
Emerald Rapids without HWP support and adjust it to utilize EPP values
supplied by the platform firmware, fix issues, clean up code and
improve documentation.
The most significant fix addresses deadlocks in the core system-wide
resume code that occur if async_schedule_dev() attempts to run its
argument function synchronously (for example, due to a memory
allocation failure). It rearranges the code in question which may
increase the system resume time in some cases, but this basically is a
removal of a premature optimization. That optimization will be added
back later, but properly this time.
Specifics:
- Add support for the Sierra Forest, Grand Ridge and Meteorlake SoCs
to the intel_idle cpuidle driver (Artem Bityutskiy, Zhang Rui)
- Do not enable interrupts when entering idle in the haltpoll cpuidle
driver (Borislav Petkov)

Merge tag 'thermal-6.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull thermal control updates from Rafael Wysocki:
"These add support for the D1/T113s THS controller to the sun8i driver
and a DT-based mechanism for platforms to indicate a preference to
reboot (instead of shutting down) on crossing a critical trip point,
fix issues, make other improvements (in the IPA governor, the Intel
HFI driver, the exynos driver and the thermal netlink interface among
other places) and clean up code.
One long-standing issue addressed here is that trip point crossing
notifications sent to user space might be unreliable due to the
incorrect handling of trip point hysteresis in the thermal core:
multiple notifications might be sent for the same event or there might
be events without any notification at all.
Specifics:
- Add dynamic thresholds for trip point crossing detection to prevent
trip point crossing notifications from being sent at incorrect
times or not at all in some cases (Rafael J. Wysocki)
- Fix synchronization issues related to the resume of thermal zones
during a system-wide resume and allow thermal zones to be resumed
concurrently (Rafael J. Wysocki)
- Modify the thermal zone unregistration to wait for the given zone
to go away completely before returning to the caller and rework the
sysfs interface for trip points on top of that (Rafael J. Wysocki)
- Fix a possible NULL pointer dereference in thermal zone
registration error path (Rafael J. Wysocki)
- Clean up the IPA thermal governor and modify it (with the help of a
new governor callback) to avoid allocating and freeing memory every
time its throttling callback is invoked (Lukasz Luba)
- Make the IPA thermal governor handle thermal instance weight
changes via sysfs correctly (Lukasz Luba)
- Update the thermal netlink code to avoid sending messages if there
are no recipients (Stanislaw Gruszka)

- Fix compilation warning in the tmon utility (Florian Eckert)
- Add support for interrupt-based thermal configuration on Exynos
along with a set of related cleanups (Mateusz Majewski)
- Make the Intel HFI thermal driver enable an HFI instance (eg.
processor package) from its first online CPU and disable it when
the last CPU in it goes offline (Ricardo Neri)
- Fix a kernel-doc warning and a spello in the cpuidle_cooling

it take a const pointer argument (Rafael J. Wysocki)"

Merge tag 'acpi-6.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull ACPI updates from Rafael Wysocki:
"From the new features standpoint, the most significant change here is
the addition of CSI-2 and MIPI DisCo for Imaging support to the ACPI
device enumeration code that will allow MIPI cameras to be enumerated
through the platform firmware on systems using ACPI.
Also significant is the switch-over to threaded interrupt handlers for
the ACPI SCI and the dedicated EC interrupt (on systems where the
former is not used) which essentially allows all ACPI code to run with
local interrupts enabled. That should improve responsiveness
significantly on systems where multiple GPEs are enabled and the
handling of one SCI involves many I/O address space accesses which
previously had to be carried out in one go with disabled interrupts on
the local CPU.
Apart from the above, the ACPI thermal zone driver will use the
Thermal fast Sampling Period (_TFP) object if available, which should
allow temperature changes to be followed more accurately on some
systems, the ACPI Notify () handlers can run on all CPUs (not just on
CPU0), which should generally speed up the processing of events
signaled through the ACPI SCI, and the ACPI power button driver will
trigger wakeup key events via the input subsystem (on systems where it
is a system wakeup device)
In addition to that, there are the usual bunch of fixes and cleanups.
Specifics:
- Add CSI-2 and DisCo for Imaging support to the ACPI device
enumeration code (Sakari Ailus, Rafael J. Wysocki)
- Adjust the cpufreq thermal reduction algorithm in the ACPI
processor driver for Tegra241 (Srikar Srimath Tirumala, Arnd
Bergmann)
- Make acpi_proc_quirk_mwait_check() x86-specific (Rafael J. Wysocki)
- Switch over ACPI to using a threaded interrupt handler for the SCI
(Rafael J. Wysocki)
- Allow ACPI Notify () handlers to run on all CPUs and clean up the
ACPI interface for deferred events processing (Rafael J. Wysocki)
- Switch over the ACPI EC driver to using a threaded handler for the
dedicated IRQ on systems without the EC GPE (Rafael J. Wysocki)
- Adjust code using ACPICA spinlocks and the ACPI EC driver spinlock
to keep local interrupts on (Rafael J. Wysocki)
- Adjust the USB4 _OSC handshake to correctly handle cases in which
certain types of OS control are denied by the platform (Mika
Westerberg)
- Correct and clean up the generic function for parsing ACPI
data-only tables with array structure (Yuntao Wang)
- Modify acpi_dev_uid_match() to support different types of its
second argument and adjust its users accordingly (Raag Jadav)
- Clean up code related to acpi_evaluate_reference() and ACPI device
lists (Rafael J. Wysocki)
- Use generic ACPI helpers for evaluating trip point temperature
objects in the ACPI thermal zone driver (Rafael J. Wysockii, Arnd
Bergmann)
- Add Thermal fast Sampling Period (_TFP) support to the ACPI thermal
zone driver (Jeff Brasen)
- Modify the ACPI LPIT table handling code to avoid u32
multiplication overflows in state residency computations (Nikita
Kiryushin)
- Drop an unused helper function from the ACPI backlight (video)
driver and add a clarifying comment to it (Hans de Goede)
- Update the ACPI backlight driver to avoid using uninitialized
memory in some cases (Nikita Kiryushin)
- Add ACPI backlight quirk for the Colorful X15 AT 23 laptop (Yuluo
Qiu)
- Add support for vendor-defined error types to the ACPI APEI error
injection code (Avadhut Naik)
- Adjust APEI to properly set MF_ACTION_REQUIRED on synchronous
memory failure events, so they are handled differently from the
asynchronous ones (Shuai Xue)
- Fix NULL pointer dereference check in the ACPI extlog driver
(Prarit Bhargava)
- Adjust the ACPI extlog driver to clear the Extended Error Log
status when RAS_CEC handled the error (Tony Luck)
- Add IRQ override quirks for some Infinity laptops and for TongFang
GMxXGxx (David McFarland, Hans de Goede)
- Clean up the ACPI NUMA code and fix it to ensure that fake_pxm is
not the same as one of the real pxm values (Yuntao Wang)
- Fix the fractional clock divider flags in the ACPI LPSS (Intel SoC)
driver so as to prevent miscalculation of the values in the clock
divider (Andy Shevchenko)
- Adjust comments in the ACPI watchdog driver to prevent kernel-doc
from complaining during documentation builds (Randy Dunlap)
- Make the ACPI button driver send wakeup key events to user space in
addition to power button events on systems that can be woken up by
the power button (Ken Xue)
- Adjust pnpacpi_parse_allocated_vendor() to use memcpy() on a full
structure field (Dmitry Antipov)"

Pull regulator updates from Mark Brown:
"The main updates for this release are around monitoring of regulators,
largely for error handling purposes. We allow the stream of regulator
events to be seen by userspace as netlink events and allow system
integrators to describe individual regulators as system critical with
information on how long the system is expected to last on error. The
system level error handling is very much about best effort problem
mitigation rather than providing something fully robust, the initial
drive was to provide a mechanism for trying to avoid initiating any
new writes to flash once we notice the power going out.
Otherwise it's very quiet, mainly several new Qualcomm devices.
- Support for marking regulators as system critical and providing
information on how long the system might last with those regulators
in a failure state, hooked into the existing critical shutdown
error handling.
- Optional support for generating netlink events for events, there
are use cases for system monitoring UIs and error handling.
- A command line option to leave unused controllable regulators
enabled, useful for debugging. We already only disable regulators
we were explicitly given permission to control.
- Support for Quacomm MP5496, PM8010 and PM8937"

Merge tag 'lsm-pr-20240105' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/lsm
Pull security module updates from Paul Moore: - Add three new syscalls: lsm_list_modules(), lsm_get_self_attr(), and lsm_set_self_attr(). The first syscall simply lists the LSMs enabled, while the second and third get and set the current process' LSM attributes. Yes, these syscalls may provide similar functionality to what can be found under /proc or /sys, but they were designed to support multiple, simultaneaous (stacked) LSMs from the start as opposed to the current /proc based solutions which were created at a time when only one LSM was allowed to be active at a given time. We have spent considerable time discussing ways to extend the existing /proc interfaces to support multiple, simultaneaous LSMs and even our best ideas have been far too ugly to support as a kernel API; after +20 years in the kernel, I felt the LSM layer had established itself enough to justify a handful of syscalls. Support amongst the individual LSM developers has been nearly unanimous, with a single objection coming from Tetsuo (TOMOYO) as he is worried that the LSM_ID_XXX token concept will make it more difficult for out-of-tree LSMs to survive. Several members of the LSM community have demonstrated the ability for out-of-tree LSMs to continue to exist by picking high/unused LSM_ID values as well as pointing out that many kernel APIs rely on integer identifiers, e.g. syscalls (!), but unfortunately Tetsuo's objections remain. My personal opinion is that while I have no interest in penalizing out-of-tree LSMs, I'm not going to penalize in-tree development to support out-of-tree development, and I view this as a necessary step forward to support the push for expanded LSM stacking and reduce our reliance on /proc and /sys which has occassionally been problematic for some container users. Finally, we have included the linux-api folks on (all?) recent revisions of the patchset and addressed all of their concerns. - Add a new security_file_ioctl_compat() LSM hook to handle the 32-bit ioctls on 64-bit systems problem. This patch includes support for all of the existing LSMs which provide ioctl hooks, although it turns out only SELinux actually cares about the individual ioctls. It is worth noting that while Casey (Smack) and Tetsuo (TOMOYO) did not give explicit ACKs to this patch, they did both indicate they are okay with the changes. - Fix a potential memory leak in the CALIPSO code when IPv6 is disabled at boot. While it's good that we are fixing this, I doubt this is something users are seeing in the wild as you need to both disable IPv6 and then attempt to configure IPv6 labeled networking via NetLabel/CALIPSO; that just doesn't make much sense. Normally this would go through netdev, but Jakub asked me to take this patch and of all the trees I maintain, the LSM tree seemed like the best fit. - Update the LSM MAINTAINERS entry with additional information about our process docs, patchwork, bug reporting, etc. I also noticed that the Lockdown LSM is missing a dedicated MAINTAINERS entry so I've added that to the pull request. I've been working with one of the major Lockdown authors/contributors to see if they are willing to step up and assume a Lockdown maintainer role; hopefully that will happen soon, but in the meantime I'll continue to look after it. - Add a handful of mailmap entries for Serge Hallyn and myself. * tag 'lsm-pr-20240105' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/lsm: (27 commits) lsm: new security_file_ioctl_compat() hook lsm: Add a __counted_by() annotation to lsm_ctx.ctx calipso: fix memory leak in netlbl_calipso_add_pass() selftests: remove the LSM_ID_IMA check in lsm/lsm_list_modules_test MAINTAINERS: add an entry for the lockdown LSM MAINTAINERS: update the LSM entry mailmap: add entries for Serge Hallyn's dead accounts mailmap: update/replace my old email addresses lsm: mark the lsm_id variables are marked as static lsm: convert security_setselfattr() to use memdup_user() lsm: align based on pointer length in lsm_fill_user_ctx() lsm: consolidate buffer size handling into lsm_fill_user_ctx() lsm: correct error codes in security_getselfattr() lsm: cleanup the size counters in security_getselfattr() lsm: don't yet account for IMA in LSM_CONFIG_COUNT calculation lsm: drop LSM_ID_IMA LSM: selftests for Linux Security Module syscalls SELinux: Add selfattr hooks AppArmor: Add selfattr hooks Smack: implement setselfattr and getselfattr hooks ... |

Pull slab updates from Vlastimil Babka:
- SLUB: delayed freezing of CPU partial slabs (Chengming Zhou)
Freezing is an operation involving double_cmpxchg() that makes a slab
exclusive for a particular CPU. Chengming noticed that we use it also
in situations where we are not yet installing the slab as the CPU
slab, because freezing also indicates that the slab is not on the
shared list. This results in redundant freeze/unfreeze operation and
can be avoided by marking separately the shared list presence by
reusing the PG_workingset flag.
This approach neatly avoids the issues described in

Pull cgroup updates from Tejun Heo: - Yafang Shao added task_get_cgroup1() helper to enable a similar BPF helper so that BPF progs can be more useful on cgroup1 hierarchies. While cgroup1 is mostly in maintenance mode, this addition is very small while having an outsized usefulness for users who are still on cgroup1. Yafang also optimized root cgroup list access by making it RCU protected in the process. - Waiman Long optimized rstat operation leading to substantially lower and more consistent lock hold time while flushing the hierarchical statistics. As the lock can be acquired briefly in various hot paths, this reduction has cascading benefits. - Waiman also improved the quality of isolation for cpuset's isolated partitions. CPUs which are allocated to isolated partitions are now excluded from running unbound work items and cpu_is_isolated() test which is used by vmstat and memcg to reduce interference now includes cpuset isolated CPUs. While it isn't there yet, the hope is eventually reaching parity with the isolation level provided by the `isolcpus` boot param but in a dynamic manner. * tag 'cgroup-for-6.8' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup: cgroup: Move rcu_head up near the top of cgroup_root cgroup/cpuset: Include isolated cpuset CPUs in cpu_is_isolated() check cgroup: Avoid false cacheline sharing of read mostly rstat_cpu cgroup/rstat: Optimize cgroup_rstat_updated_list() cgroup: Fix documentation for cpu.idle cgroup/cpuset: Expose cpuset.cpus.isolated workqueue: Move workqueue_set_unbound_cpumask() and its helpers inside CONFIG_SYSFS cgroup/rstat: Reduce cpu_lock hold time in cgroup_rstat_flush_locked() cgroup/cpuset: Take isolated CPUs out of workqueue unbound cpumask cgroup/cpuset: Keep track of CPUs in isolated partitions selftests/cgroup: Minor code cleanup and reorganization of test_cpuset_prs.sh workqueue: Add workqueue_unbound_exclude_cpumask() to exclude CPUs from wq_unbound_cpumask selftests: cgroup: Fixes a typo in a comment cgroup: Add a new helper for cgroup1 hierarchy cgroup: Add annotation for holding namespace_sem in current_cgns_cgroup_from_root() cgroup: Eliminate the need for cgroup_mutex in proc_cgroup_show() cgroup: Make operations on the cgroup root_list RCU safe cgroup: Remove unnecessary list_empty() |

Merge tag 'vfs-6.8.iov_iter' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs
Pull vfs iov_iter cleanups from Christian Brauner: "This contains a minor cleanup. The patches drop an unused argument from import_single_range() allowing to replace import_single_range() with import_ubuf() and dropping import_single_range() completely" * tag 'vfs-6.8.iov_iter' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs: iov_iter: replace import_single_range() with import_ubuf() iov_iter: remove unused 'iov' argument from import_single_range() |

Merge tag 'vfs-6.8.rw' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs
Pull vfs rw updates from Christian Brauner:
"This contains updates from Amir for read-write backing file helpers
for stacking filesystems such as overlayfs:
- Fanotify is currently in the process of introducing pre content
events. Roughly, a new permission event will be added indicating
that it is safe to write to the file being accessed. These events
are used by hierarchical storage managers to e.g., fill the content
of files on first access.
During that work we noticed that our current permission checking is
inconsistent in rw_verify_area() and remap_verify_area().
Especially in the splice code permission checking is done multiple
times. For example, one time for the whole range and then again for
partial ranges inside the iterator.
In addition, we mostly do permission checking before we call
file_start_write() except for a few places where we call it after.
For pre-content events we need such permission checking to be done
before file_start_write(). So this is a nice reason to clean this
all up.
After this series, all permission checking is done before
file_start_write().
As part of this cleanup we also massaged the splice code a bit. We
got rid of a few helpers because we are alredy drowning in special
read-write helpers. We also cleaned up the return types for splice
helpers.
- Introduce generic read-write helpers for backing files. This lifts
some overlayfs code to common code so it can be used by the FUSE
passthrough work coming in over the next cycles. Make Amir and
Miklos the maintainers for this new subsystem of the vfs"
