[Preview] [PATCH] radix tree based page cgroup [0/6]

[KAMEZAWA Hiroyuki <kamezawa.hiroyu@jp.fujitsu.com>]

Hi, this is the latest version of radix-tree based page cgroup patch.

I post this now because recent major changes are included in 2.6.25-rc4.
(I admit I should do more tests on this set.)

Almost all are rewritten and adjusted to rc4's logic.
I feel this set is simpler than previous one.

Patch series is following.
[1/6] page cgroup definition
[2/6] patch against charge/uncharge 
[3/6] patch against move_list
[4/6] patch against migration
[5/6] radix tree based page_cgroup
[6/6] boost by per-cpu cache.

 * force_empty patch is dropped because it's unnecessary.
 * vmalloc patch is dropped. we always use kmalloc in this version.

TODO:
  - add freeing page_cgroup routine. it seems necessary sometimes.
    (I have one and will be added to this set in the next post.)
  - Logic check again.

Thanks,
-Kame
