Merge tag 'xfs-6.10-merge-6' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux 

Pull xfs updates from Chandan Babu:
 "Online repair feature continues to be expanded. Also, we now support
  delayed allocation for realtime devices which have an extent size that
  is equal to filesystem's block size.

  New code:

   - Introduce Parent Pointer extended attribute for inodes

   - Bring back delalloc support for realtime devices which have an
     extent size that is equal to filesystem's block size

   - Improve performance of log incompat feature handling

  Online Repair:

   - Implement atomic file content exchanges i.e. exchange ranges of
     bytes between two files atomically

   - Create temporary files to repair file-based metadata. This uses
     atomic file content exchange facility to swap file fork mappings
     between the temporary file and the metadata inode

   - Allow callers of directory/xattr code to set an explicit owner
     number to be written into the header fields of any new blocks that
     are created. This is required to avoid walking every block of the
     new structure and modify their ownership during online repair

   - Repair more data structures:
       - Extended attributes
       - Inode unlinked state
       - Directories
       - Symbolic links
       - AGI's unlinked inode list
       - Parent pointers

   - Move Orphan files to lost and found directory

   - Fixes for Inode repair functionality

   - Introduce a new sub-AG FITRIM implementation to reduce the duration
     for which the AGF lock is held

   - Updates for the design documentation

   - Use Parent Pointers to assist in checking directories, parent
     pointers, extended attributes, and link counts

  Fixes:

   - Prevent userspace from reading invalid file data due to incorrect.
     updation of file size when performing a non-atomic clone operation

   - Minor fixes to online repair

   - Fix confusing return values from xfs_bmapi_write()

   - Fix an out of bounds access due to incorrect h_size during log
     recovery

   - Defer upgrading the extent counters in xfs_reflink_end_cow_extent()
     until we know we are going to modify the extent mapping

   - Remove racy access to if_bytes check in
     xfs_reflink_end_cow_extent()

   - Fix sparse warnings

  Cleanups:

   - Hold inode locks on all files involved in a rename until the
     completion of the operation. This is in preparation for the parent
     pointers patchset where parent pointers are applied in a separate
     chained update from the actual directory update

   - Compile out v4 support when disabled

   - Cleanup xfs_extent_busy_clear()

   - Remove unused flags and fields from struct xfs_da_args

   - Remove definitions of unused functions

   - Improve extended attribute validation

   - Add higher level directory operations helpers to remove duplication
     of code

   - Cleanup quota (un)reservation interfaces"
