[PATCH 06/13] xfs: split xfs_mod_freecounter

Christoph Hellwig
2024-03-27T11:03:45Z

xfs_mod_freecounter has two entirely separate code paths for adding or
subtracting from the free counters. Only the subtract case looks at the
rsvd flag and can return an error.

Split xfs_mod_freecounter into separate helpers for subtracting or
adding the freecounter, and remove all the impossible to reach error
handling for the addition case.
