[PATCH -mm v2 0/6] memcg/kmem: cleanup naming and callflows

Hi,

In reply to "[PATCH RFC -mm v2 3/3] memcg, slab: simplify
synchronization scheme" Johannes wrote:

So this patch set is about cleaning up memcg/kmem naming.

While preparing it I found that some of the ugly-named functions
constituting interface between memcontrol.c and slab_common.c can be
neatly got rid of w/o complicating the code. Quite the contrary, w/o
them call-flows look much simpler, IMO. So the first four patches do not
rename anything actually - they just rework call-flows in kmem cache
creation/destruction and memcg_caches arrays relocations paths. Finally,
patches 5 and 6 clean up the naming.

v1: http://lkml.org/lkml/2014/4/25/254

Changes in v2:
 - move memcg_params allocation/free for per memcg caches to
   slab_common.c, because this way it looks clearer (patch 4)
 - minor changes in function names and comments

Reviews are appreciated.

Thanks,
