Subject: [PATCH 0/9] memcg updates (14/Nov/2008)

Several patches are posted after last update (12/Nov),
it's better to catch all up as series.

All patchs are mm-of-the-moment snapshot 2008-11-13-17-22
  http://userweb.kernel.org/~akpm/mmotm/
(You may need to patch fs/dquota.c and fix kernel/auditsc.c CONFIG error)

New ones are 1,2,3 and 9. 

IMHO, patch 1-4 are ready to go. (but I want Ack from Balbir to 3/9)

Contents:

[1/9] .... fix memory online/offline with memcg.
  This patch is for "real" memory hotplug. So, people who can test this
  is limited, I think. I asked Badari to try this.
  This fix itself is logically correct I think, but there may be other bugs..

[2/9] .... reduce size of per-cpu allocation.
  This is from Jan Blunck <jblunck@...e.de> and I picked it up and rewrote.
  please test. This tries to reduce memory usage of mem_cgroup struct.

[3/9] .... add force_empty again with proper implementation.
  I removed "force_empty" by account_move patch in mmotm. But I asked not to
  do that brutal removal of interface. I'm sorry.
  This adds "force_empty", but implemntaion itself is much saner. After this,
  force_empty is no longer "debug only" interface.

[4/9] .... account swap-cache.
  Before accounting swap, we have to handle swap-cache.
  This patch have been test for a month and seems to works well. Still here
  and waiting for bug fixes moved into..

[5/9] .... mem+swap controller kconfig
  Kconfig changes and macro for mem+swap controller.

[6/9] .... swap cgroup.
  For accounting swap, we have to prepare a strage for remembering swap.

[7/9] .... mem+swap controller.
  mem+swap controller core logic. I and Nishimura have been testing this
  for a month. It's getting nicer.

[8/9] .... synchronized LRU patch
  remove mz->lru_lock and make use of zone->lru_lock. By this, we do not have to
  duplicate vmscan's global LRU behavior in memcg.
  I think I'm an only tester of this ;) but works well.

[9/9] .... mem_cgroup_disabled() patch
  Replacing if (mem_cgroup_subsys.disabled) to be if (mem_cgroup_disabled()).
  Takahashi (dm-ioband team) posted their bio-cgroup interface working with
  page_cgroup. This is cut out from his one.
  Takahashi, If you ack me, send me Signed-off-by or Acked-by. I'll queue this.

Thanks,
-Kame
