      Pull btrfs updates from David Sterba:
       "The usual mix of performance improvements and new features.
      
        The core change is reworking how checksums are processed, with
        followup cleanups and simplifications. There are two minor changes in
        block layer and iomap code.
      
        Features:
      
         - block group allocation class heuristics:
            - pack files by size (up to 128k, up to 8M, more) to avoid
              fragmentation in block groups, assuming that file size and life
              time is correlated, in particular this may help during balance
            - with tracepoints and extensible in the future
      
        Performance:
      
         - send: cache directory utimes and only emit the command when
           necessary
            - speedup up to 10x
            - smaller final stream produced (no redundant utimes commands
              issued)
            - compatibility not affected
      
         - fiemap: skip backref checks for shared leaves
            - speedup 3x on sample filesystem with all leaves shared (e.g. on
              snapshots)
      
         - micro optimized b-tree key lookup, speedup in metadata operations
           (sample benchmark: fs_mark +10% of files/sec)
      
        Core changes:
      
         - change where checksumming is done in the io path:
            - checksum and read repair does verification at lower layer
            - cascaded cleanups and simplifications
      
         - raid56 refactoring and cleanups
      
        Fixes:
      
         - sysfs: make sure that a run-time change of a feature is correctly
           tracked by the feature files
      
         - scrub: better reporting of tree block errors
      
        Other:
      
         - locally enable -Wmaybe-uninitialized after fixing all warnings
      
         - misc cleanups, spelling fixes
      
        Other code:
      
         - block: export bio_split_rw
      
         - iomap: remove IOMAP_F_ZONE_APPEND"

      Pull fsverity updates from Eric Biggers:
       "Fix the longstanding implementation limitation that fsverity was only
        supported when the Merkle tree block size, filesystem block size, and
        PAGE_SIZE were all equal.
      
        Specifically, add support for Merkle tree block sizes less than
        PAGE_SIZE, and make ext4 support fsverity on filesystems where the
        filesystem block size is less than PAGE_SIZE.
      
        Effectively, this means that fsverity can now be used on systems with
        non-4K pages, at least on ext4. These changes have been tested using
        the verity group of xfstests, newly updated to cover the new code
        paths.
      
        Also update fs/verity/ to support verifying data from large folios.
      
        There's also a similar patch for fs/crypto/, to support decrypting
        data from large folios, which I'm including in here to avoid a merge
        conflict between the fscrypt and fsverity branches"

      Pull erofs updates from Gao Xiang:
       "The most noticeable feature for this cycle is per-CPU kthread
        decompression since Android use cases need low-latency I/O handling in
        order to ensure the app runtime performance, currently unbounded
        workqueue latencies are not quite good for production on many aarch64
        hardwares and thus we need to introduce a deterministic expectation
        for these. Decompression is CPU-intensive and it is sleepable for
        EROFS, so other alternatives like decompression under softirq contexts
        are not considered. More details are in the corresponding commit
        message.
      
        Others are random cleanups around the whole codebase and we will
        continue to clean up further in the next few months.
      
        Due to Lunar New Year holidays, some other new features were not
        completely reviewed and solidified as expected and we may delay them
        into the next version.
      
        Summary:
      
         - Add per-cpu kthreads for low-latency decompression for Android use
           cases

      Pull vfs hardening update from Christian Brauner:
       "Jan pointed out that during shutdown both filp_close() and super block
        destruction will use basic printk logging when bugs are detected. This
        causes issues in a few scenarios:
      
         - Tools like syzkaller cannot figure out that the logged message
           indicates a bug.
      
         - Users that explicitly opt in to have the kernel bug on data
           corruption by selecting CONFIG_BUG_ON_DATA_CORRUPTION should see
           the kernel crash when they did actually select that option.
      
         - When there are busy inodes after the superblock is shut down later
           access to such a busy inodes walks through freed memory. It would
           be better to cleanly crash instead.
      
        All of this can be addressed by using the already existing
        CHECK_DATA_CORRUPTION() macro in these places when kernel bugs are
        detected. Its logging improvement is useful for all users.
      
        Otherwise this only has a meaningful behavioral effect when users do
        select CONFIG_BUG_ON_DATA_CORRUPTION which means this is backward
        compatible for regular users"

      Pull vfs idmapping updates from Christian Brauner:
      
       - Last cycle we introduced the dedicated struct mnt_idmap type for
         mount idmapping and the required infrastucture in 256c8aed ("fs:
         introduce dedicated idmap type for mounts"). As promised in last
         cycle's pull request message this converts everything to rely on
         struct mnt_idmap.
      
         Currently we still pass around the plain namespace that was attached
         to a mount. This is in general pretty convenient but it makes it easy
         to conflate namespaces that are relevant on the filesystem with
         namespaces that are relevant on the mount level. Especially for
         non-vfs developers without detailed knowledge in this area this was a
         potential source for bugs.
      
         This finishes the conversion. Instead of passing the plain namespace
         around this updates all places that currently take a pointer to a
         mnt_userns with a pointer to struct mnt_idmap.
      
         Now that the conversion is done all helpers down to the really
         low-level helpers only accept a struct mnt_idmap argument instead of
         two namespace arguments.
      
         Conflating mount and other idmappings will now cause the compiler to
         complain loudly thus eliminating the possibility of any bugs. This
         makes it impossible for filesystem developers to mix up mount and
         filesystem idmappings as they are two distinct types and require
         distinct helpers that cannot be used interchangeably.
      
         Everything associated with struct mnt_idmap is moved into a single
         separate file. With that change no code can poke around in struct
         mnt_idmap. It can only be interacted with through dedicated helpers.
         That means all filesystems are and all of the vfs is completely
         oblivious to the actual implementation of idmappings.
      
         We are now also able to extend struct mnt_idmap as we see fit. For
         example, we can decouple it completely from namespaces for users that
         don't require or don't want to use them at all. We can also extend
         the concept of idmappings so we can cover filesystem specific
         requirements.
      
         In combination with the vfs{g,u}id_t work we finished in v6.2 this
         makes this feature substantially more robust and thus difficult to
         implement wrong by a given filesystem and also protects the vfs.
      
       - Enable idmapped mounts for tmpfs and fulfill a longstanding request.
      
         A long-standing request from users had been to make it possible to
         create idmapped mounts for tmpfs. For example, to share the host's
         tmpfs mount between multiple sandboxes. This is a prerequisite for
         some advanced Kubernetes cases. Systemd also has a range of use-cases
         to increase service isolation. And there are more users of this.
      
         However, with all of the other work going on this was way down on the
         priority list but luckily someone other than ourselves picked this
         up.
      
         As usual the patch is tiny as all the infrastructure work had been
         done multiple kernel releases ago. In addition to all the tests that
         we already have I requested that Rodrigo add a dedicated tmpfs
         testsuite for idmapped mounts to xfstests. It is to be included into
         xfstests during the v6.3 development cycle. This should add a slew of
         additional tests.

      Merge tag 'remove-get_kernel_pages-for-6.3' of https://git.linaro.org/people/jens.wiklander/linux-tee
      
      Pull TEE update from Jens Wiklander:
       "Remove get_kernel_pages()
      
        Vmalloc page support is removed from shm_get_kernel_pages() and the
        get_kernel_pages() call is replaced by calls to get_page(). With no
        remaining callers of get_kernel_pages() the function is removed"
      
      [ This looks like it's just some random 'tee' cleanup, but the bigger
        picture impetus for this is really to to to remove historical
        confusion with mixed use of kernel virtual addresses and 'struct page'
        pointers.
      
        Kernel virtual pointers in the vmalloc space is then particularly
        confusing - both for looking up a page pointer (when trying to then
        unify a "virtual address or page" interface) and _particularly_ when
        mixed with HIGHMEM support and the kmap*() family of remapping.
      
        This is particularly true with HIGHMEM getting much less test coverage
        with 32-bit architectures being increasingly legacy targets.
      
        So we actively wanted to remove get_kernel_pages() to make sure nobody
        else used it too, and thus the 'tee' part is "finally remove last
        user".
      
        See also commit 6647e76a ("v4l2: don't fall back to follow_pfn()
        if pin_user_pages_fast() fails") for a totally different version of a
        conceptually similar "let's stop this confusion of different ways of
        referring to memory".   - Linus ]

      Pull arm64 regression fix from Will Deacon:
       "Apologies for the _extremely_ late pull request here, but we had a
        'perf' (i.e. CPU PMU) regression on the Apple M1 reported on Wednesday
        [1] which was introduced by bd275681 ("perf: Rewrite core context
        handling") during the merge window.
      
        Mark and I looked into this and noticed an additional problem caused
        by the same patch, where the 'CHAIN' event (used to combine two
        adjacent 32-bit counters into a single 64-bit counter) was not being
        filtered correctly. Mark posted a series on Thursday [2] which
        addresses both of these regressions and I queued it the same day.
      
        The changes are small, self-contained and have been confirmed to fix
        the original regression.
      
        Summary:
      
         - Fix 'perf' regression for non-standard CPU PMU hardware (i.e. Apple
           M1)"
