Merge tag 'slab-for-7.2-part2' of git://git.kernel.org/pub/scm/linux/kernel/git/vbabka/slab

Pull more slab updates from Vlastimil Babka:

 - Introduce and wire up a new alloc_flags parameter for modifying
   slab-specific behavior without adding or reusing gfp flags. Also
   introduce slab_alloc_context to keep function parameter bloat in
   check. Both are similar to what the page allocator does.
   kmalloc_flags() exposes alloc_flags for mm-internal users.

     - SLAB_ALLOC_NOLOCK flag is used to implement kmalloc_nolock()
       behavior without relying on lack of __GFP_RECLAIM, which caused
       false positives with workarounds like fd3634312a04 ("debugobject:
       Make it work with deferred page initialization - again").

     - SLAB_ALLOC_NO_RECURSE replaces __GFP_NO_OBJ_EXT, which could have
       been removed, but pending memory allocation profiling changes in
       mm tree have grown a new user - there is however a work ongoing
       to replace that too, so __GFP_NO_OBJ_EXT should eventually be
       removed. (Vlastimil Babka)

 - Add kmem_buckets_alloc_track_caller() with a user to be added in the
   net tree (Pedro Falcato)

 - Fixes for kernel-doc and slabinfo (Randy Dunlap, Yichong Chen)
