Hi Dave,

Please pull this branch with changes for xfs.

As usual, I did a test-merge with the main upstream branch as of a few
minutes ago, and didn't see any conflicts.  Please let me know if you
encounter any problems.

The following changes since commit efc0845f5d3e253f7f46a60b66a94c3164d76ee3:

xfs: convert xfs_ialloc_has_inodes_at_extent to return keyfill scan results (2023-04-11 19:00:15 -0700)

are available in the Git repository at:

for you to fetch changes up to 30f8ee5e7e0ccce396dff209c6cbce49d0d7e167:

xfs: ensure that single-owner file blocks are not owned by others (2023-04-11 19:00:16 -0700)

----------------------------------------------------------------
xfs: detect incorrect gaps in rmap btree [v24.5]

Following in the theme of the last two patchsets, this one strengthens
the rmap btree record checking so that scrub can count the number of
space records that map to a given owner and that do not map to a given
owner.  This enables us to determine exclusive ownership of space that
can't be shared.

xfs: teach scrub to check for sole ownership of metadata objects
xfs: ensure that single-owner file blocks are not owned by others
