Merge tag 'for-6.20-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux

Pull btrfs updates from David Sterba:
 "User visible changes, feature updates:

   - when using block size > page size, enable direct IO

   - fallback to buffered IO if the data profile has duplication,
     workaround to avoid checksum mismatches on block group profiles
     with redundancy, real direct IO is possible on single or RAID0

   - redo export of zoned statistics, moved from sysfs to
     /proc/pid/mountstats due to size limitations of the former

  Experimental features:

   - remove offload checksum tunable, intended to find best way to do it
     but since we've switched to offload to thread for everything we
     don't need it anymore

   - initial support for remap-tree feature, a translation layer of
     logical block addresses that allow changes without moving/rewriting
     blocks to do eg. relocation, or other changes that require COW

  Notable fixes:

   - automatic removal of accidentally leftover chunks when
     free-space-tree is enabled since mkfs.btrfs v6.16.1

   - zoned mode:
      - do not try to append to conventional zones when RAID is mixing
        zoned and conventional drives
      - fixup write pointers when mixing zoned and conventional on
        DUP/RAID* profiles

   - when using squota, relax deletion rules for qgroups with 0 members
     to allow easier recovery from accounting bugs, also add more checks
     to detect bad accounting

   - fix periodic reclaim scanning, properly check boundary conditions
     not to trigger it unexpectedly or miss the time to run it

   - trim:
      - continue after first error
      - change reporting to the first detected error
      - add more cancellation points
      - reduce contention of big device lock that can block other
        operations when there's lots of trimmed space

   - when chunk allocation is forced (needs experimental build) fix
     transaction abort when unexpected space layout is detected

  Core:

   - switch to crypto library API for checksumming, removed module
     dependencies, pointer indirections, etc.

   - error handling improvements

   - adjust how and where transaction commit or abort are done and are
     maybe not necessary

   - minor compression optimization to skip single block ranges

   - improve how compression folios are handled

   - new and updated selftests

   - cleanups, refactoring:
      - auto-freeing and other automatic variable cleanup conversion
      - structure size optimizations
      - condition annotations"
