Hi Carlos,

Please pull this branch with changes for xfs for 6.13-rc1.

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.

xfs: repair metadata directory file path connectivity (2024-11-05 13:38:35 -0800)

----------------------------------------------------------------
xfs: metadata inode directory trees [v5.5 03/10]

This series delivers a new feature -- metadata inode directories.  This
is a separate directory tree (rooted in the superblock) that contains
only inodes that contain filesystem metadata.  Different metadata
objects can be looked up with regular paths.

Start by creating xfs_imeta{dir,file}* functions to mediate access to
the metadata directory tree.  By the end of this mega series, all
existing metadata inodes (rt+quota) will use this directory tree instead
of the superblock.

Next, define the metadir on-disk format, which consists of marking
inodes with a new iflag that says they're metadata.  This prevents
bulkstat and friends from ever getting their hands on fs metadata files.

With a bit of luck, this should all go splendidly.
