Merge tag 'for-5.18-tag' of git://git./linux/kernel/git/kdave/linux

Pull btrfs updates from David Sterba:
 "This contains feature updates, performance improvements, preparatory
  and core work and some related VFS updates:

  Features:

   - encoded read/write ioctls, allows user space to read or write raw
     data directly to extents (now compressed, encrypted in the future),
     will be used by send/receive v2 where it saves processing time

   - zoned mode now works with metadata DUP (the mkfs.btrfs default)

   - error message header updates:
      - print error state: transaction abort, other error, log tree
        errors
      - print transient filesystem state: remount, device replace,
        ignored checksum verifications

   - tree-checker: verify the transaction id of the to-be-written dirty
     extent buffer

  Performance improvements for fsync:

   - directory logging speedups (up to -90% run time)

   - avoid logging all directory changes during renames (up to -60% run
     time)

   - avoid inode logging during rename and link when possible (up to
     -60% run time)

   - prepare extents to be logged before locking a log tree path
     (throughput +7%)

   - stop copying old file extents when doing a full fsync()

   - improved logging of old extents after truncate

  Core, fixes:

   - improved stale device identification by dev_t and not just path
     (for devices that are behind other layers like device mapper)

   - continued extent tree v2 preparatory work
      - disable features that won't work yet
      - add wrappers and abstractions for new tree roots

   - improved error handling

   - add super block write annotations around background block group
     reclaim

   - fix device scanning messages potentially accessing stale pointer

   - cleanups and refactoring

  VFS:

   - allow reflinks/deduplication from two different mounts of the same
     filesystem

   - export and add helpers for read/write range verification, for the
     encoded ioctls"
