gargh.  CONFIG_MEMCG_KMEM, please!

Here too. I like it as much as you do.

But that is consistent with the rest of the file, and I'd rather have
it this way.

There's not much point in being consistent with something which is so
unpleasant.  I'm on a little campaign to rename
CONFIG_CGROUP_MEM_RES_CTLR to CONFIG_MEMCG, only nobody has taken my
bait yet.  Be first!

+1.

Block cgroup recently did blkio / blkiocg / blkio_cgroup -> blkcg.
Join the cool crowd!  :P
