Merge tag 'for-6.18-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux

Pull btrfs updates from David Sterba:
 "There are no new features, the changes are in the core code, notably
  tree-log error handling and reporting improvements, and initial
  support for block size > page size.

  Performance improvements:

   - search data checksums in the commit root (previous transaction) to
     avoid locking contention, this improves parallelism of read
     heavy/low write workloads, and also reduces transaction commit
     time; on real and reproducer workload the sync time went from
     minutes to tens of seconds (workload and numbers are in the
     changelog)

  Core:

   - tree-log updates:
      - error handling improvements, transaction aborts
      - add new error state 'O' (printed in status messages) when log
        replay fails and is aborted
      - reduced number of btrfs_path allocations when traversing the
        tree

   - 'block size > page size' support
      - basic implementation with limitations, under experimental build
      - limitations: no direct io, raid56, encoded read (standalone and
        in send ioctl), encoded write
      - preparatory work for compression, removing implicit assumptions
        of page and block sizes
      - compression workspaces are now per-filesystem, we cannot assume
        common block size for work memory among different filesystems

   - tree-checker now verifies INODE_EXTREF item (which is implementing
     hardlinks)

   - tree leaf pretty printer updates, there were missing data from
     items, keys/items

   - move config option CONFIG_BTRFS_REF_VERIFY to CONFIG_BTRFS_DEBUG,
     it's a debugging feature and not needed to be enabled separately

   - more struct btrfs_path auto free updates

   - use ref_tracker API for tracking delayed inodes, enabled by mount
     option 'ref_verify', allowing to better pinpoint leaking references

   - in zoned mode, avoid selecting data relocation zoned for ordinary
     data block groups

   - updated and enhanced error messages

   - lots of cleanups and refactoring"
