[PATCH 0/2] mm, slab: Extend vm/drop_caches to shrink kmem slabs

[Waiman Long]

The purpose of this patchset is to allow system administrators to have
the ability to shrink all the kmem slabs in order to free up memory
and get a more accurate picture of how many slab objects are actually
being used.

Patch 1 adds a new memcg_iterate_all() that is used by the patch 2 to
iterate on all the memory cgroups.

Waiman Long (2):
  mm, memcontrol: Add memcg_iterate_all()
  mm, slab: Extend vm/drop_caches to shrink kmem slabs
