* 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.

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"
