With recent fixes for the permission checking when moving a task into a cgroup
using a file descriptor to a cgroup's cgroup.procs file and calling write() it
seems a good idea to clarify CLONE_INTO_CGROUP permission checking with a
comment.

As previously discussed(https://lkml.org/lkml/2022/1/20/51),
cpuset_attach() is affected with similar cpu hotplug race,
as follow scenario:

     cpuset_attach()				cpu hotplug
    ---------------------------            ----------------------
    down_write(cpuset_rwsem)
    guarantee_online_cpus() // (load cpus_attach)
					sched_cpu_deactivate
					  set_cpu_active()
					  // will change cpu_active_mask
    set_cpus_allowed_ptr(cpus_attach)
      __set_cpus_allowed_ptr_locked()
       // (if the intersection of cpus_attach and
         cpu_active_mask is empty, will return -EINVAL)
    up_write(cpuset_rwsem)

To avoid races such as described above, protect cpuset_attach() call
with cpu_hotplug_lock.

It was found that a "suspicious RCU usage" lockdep warning was issued
with the rcu_read_lock() call in update_sibling_cpumasks().  It is
because the update_cpumasks_hier() function may sleep. So we have
to release the RCU lock, call update_cpumasks_hier() and reacquire
it afterward.

Also add a percpu_rwsem_assert_held() in update_sibling_cpumasks()
instead of stating that in the comment.

The commit 1f1562fc ("cgroup/cpuset: Don't let child cpusets

on the default hierarchy (or v2 mode) but it dropped the check in v1
too.

This patch returns and separates the legacy-only validations so that
they can be considered only in the v1 mode, which should enforce the old
constraints for the sake of compatibility.

Pull btrfs updates from David Sterba:
 "This end of the year branch is intentionally not that exciting. Most
  of the changes are under the hood, but there are some minor user
  visible improvements and several performance improvements too.

  Features:

   - make send work with concurrent block group relocation.

     We're not allowed to prevent send failing or silently producing
     some bad stream but with more fine grained locking and checks it's
     possible. The send vs deduplication exclusion could reuse the same
     logic in the future.

   - new exclusive operation 'balance paused' to allow adding a device
     to filesystem with paused balance

   - new sysfs file for fsid stored in the per-device directory to help
     distinguish devices when seeding is enabled, the fsid may differ
     from the one reported by the filesystem

  Performance improvements:

   - less metadata needed for directory logging, directory deletion is
     20-40% faster

   - in zoned mode, cache zone information during mount to speed up
     repeated queries (about 50% speedup)

   - free space tree entries get indexed and searched by size (latency
     -30%, search run time -30%)

   - less contention in tree node locking when inserting a key and no
     splits are needed (files/sec in fsmark improves by 1-20%)

  Fixes:

   - fix ENOSPC failure when attempting direct IO write into NOCOW range

   - fix deadlock between quota enable and other quota operations

   - global reserve minimum calculations fixed to account for free space
     tree

   - in zoned mode, fix condition for chunk allocation that may not find
     the right zone for reuse and could lead to early ENOSPC

  Core:

   - global reserve stealing got simplified and cleaned up in evict

   - remove async transaction commit based on manual transaction refs,
     reuse existing kthread and mechanisms to let it commit transaction
     before timeout

   - preparatory work for extent tree v2, add wrappers for global tree
     roots, truncation path cleanups

   - remove readahead framework, it's a bit overengineered and used only
     for scrub, and yet it does not cover all its needs, there is
     another readahead built in the b-tree search that is now used,
     performance drop on HDD is about 5% which is acceptable and scrub
     is often throttled anyway, on SSDs there's no reported drop but
     slight improvement

   - self tests report extent tree state when error occurs

   - replace assert with debugging information when an uncommitted
     transaction is found at unmount time

   - error handling improvements

   - other cleanups and refactoring"

Pull fs idmapping updates from Christian Brauner:
 "This contains the work to enable the idmapping infrastructure to
  support idmapped mounts of filesystems mounted with an idmapping.

  In addition this contains various cleanups that avoid repeated
  open-coding of the same functionality and simplify the code in quite a
  few places.

  We also finish the renaming of the mapping helpers we started a few
  kernel releases back and move them to a dedicated header to not
  continue polluting the fs header needlessly with low-level idmapping
  helpers. With this series the fs header only contains idmapping
  helpers that interact with fs objects.

  Currently we only support idmapped mounts for filesystems mounted
  without an idmapping themselves. This was a conscious decision
  mentioned in multiple places (cf. [1]).

  As explained at length in [3] it is perfectly fine to extend support
  for idmapped mounts to filesystem's mounted with an idmapping should
  the need arise. The need has been there for some time now (cf. [2]).

  Before we can port any filesystem that is mountable with an idmapping
  to support idmapped mounts in the coming cycles, we need to first
  extend the mapping helpers to account for the filesystem's idmapping.
  This again, is explained at length in our documentation at [3] and
  also in the individual commit messages so here's an overview.

  Currently, the low-level mapping helpers implement the remapping
  algorithms described in [3] in a simplified manner as we could rely on
  the fact that all filesystems supporting idmapped mounts are mounted
  without an idmapping.

  In contrast, filesystems mounted with an idmapping are very likely to
  not use an identity mapping and will instead use a non-identity
  mapping. So the translation step from or into the filesystem's
  idmapping in the remapping algorithm cannot be skipped for such
  filesystems.

  Non-idmapped filesystems and filesystems not supporting idmapped
  mounts are unaffected by this change as the remapping algorithms can
  take the same shortcut as before. If the low-level helpers detect that
  they are dealing with an idmapped mount but the underlying filesystem
  is mounted without an idmapping we can rely on the previous shortcut
  and can continue to skip the translation step from or into the
  filesystem's idmapping. And of course, if the low-level helpers detect
  that they are not dealing with an idmapped mount they can simply
  return the relevant id unchanged; no remapping needs to be performed
  at all.

  These checks guarantee that only the minimal amount of work is
  performed. As before, if idmapped mounts aren't used the low-level
  helpers are idempotent and no work is performed at all"

Pull gpio updates from Bartosz Golaszewski:
 "The gpio-sim module is back, this time without any changes to
  configfs. This results in a less elegant user-space interface but I
  never got any follow-up on the committable items and didn't want to
  delay this module for several more months.

  Other than that we have support for several new models and some
  support going away. We started working on converting GPIO drivers to
  using fwnode exclusively in order to limit references to OF symbols to
  gpiolib-of.c exclusively. We also have regular tweaks and improvements
  all over the place.

  Summary:

   - new testing module: gpio-sim that is scheduled to replace
     gpio-mockup

   - initial changes aiming at converting all GPIO drivers to using the
     fwnode interface and limiting any references to OF symbols to
     gpiolib-of.c

   - add support for Tegra234 and Tegra241 to gpio-tegra186

   - add support for new models (SSD201 and SSD202D) to gpio-msc313

   - add basic support for interrupts to gpio-aggregator

   - add support for AMDIF031 HID device to gpio-amdpt

   - drop support for unused platforms in gpio-xlp

   - cleanup leftovers from the removal of the legacy Samsung Exynos
     GPIO driver

   - use raw spinlocks in gpio-aspeed and gpio-aspeed-sgpio to make
     PREEMPT_RT happy

   - generalize the common 'ngpios' device property by reading it in the
     core gpiolib code so that we can remove duplicate reads from
     drivers

   - allow line names from device properties to override names set by
     drivers

   - code shrink in gpiod_add_lookup_table()

   - add new model to the DT bindings for gpio-vf610

   - convert DT bindings for tegra devices to YAML

   - improvements to interrupt handling in gpio-rcar and gpio-rockchip

   - updates to intel drivers from Andy (details in the merge commit)

   - some minor tweaks, improvements and coding-style fixes all around

Pull trivial tree removal from Jiri Kosina:
 "Remove any mentions of trivial tree from the documentation and
  MAINTAINERS.

  This has been discussed on ksummit-discuss@ some time ago (link is
  provided in the commit message, together with the reasoning). It's a
  general agreement that reason for such a tree to exist is currently
  pretty much non-existent"
