| |
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@suse.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
