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.
