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

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
