#     Merge tag 'xfs-5.16-merge-4' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux
#     
#     Pull xfs updates from Darrick Wong:
#      "This cycle we've worked on fixing bugs and improving XFS' memory
#       footprint.
#     
#       The most notable fixes include: fixing a corruption warning (and free
#       space accounting skew) if copy on write fails; fixing slab cache
#       misuse if SLOB is enabled, which apparently was broken for years
#       without anybody noticing; and fixing a potential race with online
#       shrinkfs.
#     
#       Otherwise, the bulk of the changes here involve setting up separate
#       slab caches for frequently used items such as btree cursors and log
#       intent items, and compacting the structures to reduce memory usage of
#       those items substantially. This also sets us up to support larger
#       btrees in future kernels. We also switch parts of online fsck to
#       allocate scrub context information from the heap instead of using
#       stack space.
#     
#       Summary:
#     
#        - Bug fixes and cleanups for kernel memory allocation usage, this
#          time without touching the mm code.
#     
#        - Refactor the log recovery mechanism that preserves held resources
#          across a transaction roll so that it uses the exact same mechanism
#          that we use for that during regular runtime.
#     
#        - Fix bugs and tighten checking around btree heights.
#     
#        - Remove more old typedefs.
#     
#        - Fix perag reference leaks when racing with growfs.
#     
#        - Remove unused fields from xfs_btree_cur.
#     
#        - Allocate various scrub structures on the heap to reduce stack
#          usage.
#     
#        - Pack xfs_btree_cur fields and rearrange to support arbitrary
#          heights.
#     
#        - Compute maximum possible heights for each btree height, and use
#          that to set up slab caches for each btree type.
#     
#        - Finally remove kmem_zone_t, since these have always been struct
#          kmem_cache on Linux.
#     
#        - Compact the structures used to coordinate work intent items.
#     
#        - Set up slab caches for each work intent item type.
#     
#        - Rename the "bmap_add_free" function to "free_extent_later", which
#          more accurately describes what it does.
#     
#        - Fix corruption warning on unmount when a CoW preallocation covers a
#          data fork delalloc reservation but then the CoW fails.
#     
#        - Add some more minor code improvements"
