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" * tag 'xfs-5.16-merge-4' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux: (45 commits) xfs: use swap() to make code cleaner xfs: Remove duplicated include in xfs_super xfs: punch out data fork delalloc blocks on COW writeback failure xfs: remove unused parameter from refcount code xfs: reduce the size of struct xfs_extent_free_item xfs: rename xfs_bmap_add_free to xfs_free_extent_later xfs: create slab caches for frequently-used deferred items xfs: compact deferred intent item structures xfs: rename _zone variables to _cache xfs: remove kmem_zone typedef xfs: use separate btree cursor cache for each btree type xfs: compute absolute maximum nlevels for each btree type xfs: kill XFS_BTREE_MAXLEVELS xfs: compute the maximum height of the rmap btree when reflink enabled xfs: clean up xfs_btree_{calc_size,compute_maxlevels} xfs: compute maximum AG btree height for critical reservation calculation xfs: rename m_ag_maxlevels to m_allocbt_maxlevels xfs: dynamically allocate cursors based on maxlevels xfs: encode the max btree height in the cursor xfs: refactor btree cursor allocation function ...
