Subject[PATCH 0/12] memcg updates v5
Hi, I updated the stack and reflected comments.
Against the latest mmotm. (rc7-mm1)

Major changes from previous one is
- page_cgroup allocation/lookup manner is changed.
- force_empty is totally rewritten. and a problem that "force_empty takes long time"
in previous version is fixed (I think...)
- reordered patches.
- first half are easy ones.
- second half are big ones.

I'm still testing with full debug option. No problem found yet.
(I'm afraid of race condition which have not been caught yet.)

[1/12] avoid accounting special mappings not on LRU. (fix)
[2/12] move charege() call to swapped-in page under lock_page() (clean up)
[3/12] make root cgroup to be unlimited. (change semantics.)
[4/12] make page->mapping NULL before calling uncharge (clean up)
[5/12] make page->flags to use atomic ops. (changes in infrastructure)
[6/12] optimize stat. (clean up)
[7/12] add support function for moving account. (new function)
[8/12] rewrite force_empty to use move_account. (change semantics.)
[9/12] allocate all page_cgroup at boot. (changes in infrastructure)
[10/12] free page_cgroup from LRU in lazy way (optimize)
[11/12] add page_cgroup to LRU in lazy way (optimize)
[12/12] fix race at charging swap (fix by new logic.)

*Any* comment is welcome.
