Subject: [PATCH mm-unstable v3 0/2] memcg_kmem hooks refactoring

Hi,

sorry for a v3 that soon after v2. I initially planned to just merge the
v2 to the slab tree later this week, but then I checked and the
conflicts with mm tree would be too tedious (mainly due to memory
allocation profiling series). Also large part of this is in memcontrol.c
and further work in there might be based on this, so it's easier to just
go via mm tree.

So this is just a rebase on top of mm-unstable so it can be included
there. Thanks.

Vlastimil
