Linus Torvalds 86ba24c41a Merge tag 'slab-for-7.2-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/vbabka/slab 
Pull slab fixes from Vlastimil Babka:

 - Prevent unbounded recursion in free path with memory allocation
   profiling, which has caused a stack overflow on a Meta production
   host due to a 125-deep __free_slab<->kfree recursion (Harry Yoo)

 - Fix type-based partitioning confusing sparse which does not know
   __builtin_infer_alloc_token() (Marco Elver)

 - Fix a potential memory leak in bulk freeing path on NUMA machines
   (Shengming Hu)

* tag 'slab-for-7.2-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/vbabka/slab:
  slab: silence sparse warning with type-based partitioning
  mm/slab: prevent unbounded recursion in free path with new kmalloc type
  lib/alloc_tag: introduce mem_alloc_profiling_permanently_disabled()
  mm/slab: decouple SLAB_NO_SHEAVES from SLAB_NO_OBJ_EXT
  mm/slab: fix a memory leak due to bootstrapping sheaves twice
  mm/slub: fix lost local objects when bulk remote free batch fills
