      Pull scheduler updates from Borislav Petkov:
       "Mostly minor things this time; some highlights:
      
         - core-sched: Add 'Forced Idle' accounting; this allows to track how
           much CPU time is 'lost' due to core scheduling constraints.
      
         - psi: Fix for MEM_FULL; a task running reclaim would be counted as a
           runnable task and prevent MEM_FULL from being reported.
      
         - cpuacct: Long standing fixes for some cgroup accounting issues.
      
         - rt: Bandwidth timer could, under unusual circumstances, be failed
           to armed, leading to indefinite throttling."

      Pull xfs updates from Darrick Wong:
       "The big new feature here is that the mount code now only bothers to
        try to free stale COW staging extents if the fs unmounted uncleanly.
        This should reduce mount times, particularly on filesystems supporting
        reflink and containing a large number of allocation groups.
      
        Everything else this cycle are bugfixes, as the iomap folios
        conversion should be plenty enough excitement for anyone. That and I
        ran out of brain bandwidth after Thanksgiving last year.

         - Fix log recovery with da btree buffers when metauuid is in use.
      
         - Fix type coercion problems in xattr buffer size validation.
      
         - Fix a bug in online scrub dir leaf bestcount checking.
      
         - Only run COW recovery when recovering the log.
      
         - Fix symlink target buffer UAF problems and symlink locking problems
           by not exposing xfs innards to the VFS.
      
         - Fix incorrect quotaoff lock usage.
      
         - Don't let transactions cancel cleanly if they have deferred work
           items attached.
      
         - Fix a UAF when we're deciding if we need to relog an intent item.
      
         - Reduce kvmalloc overhead for log shadow buffers.
      
         - Clean up sysfs attr group usage.
      
         - Fix a bug where scrub's bmap/rmap checking could race with a quota
           file block allocation due to insufficient locking.
      
         - Teach scrub to complain about invalid project ids"

      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
      
        Other:

      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"
