  git://git.kernel.org/pub/scm/linux/kernel/git/vbabka/slab.git tags/slab-for-7.2-rc4

Thanks,
Vlastimil

======================================

- 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)
