This patch set is for memory resource controller. 4 purposes here. - improve performance of memcg. - remove lock_page_cgroup() - making page_cgroup->flags to be atomic_ops. - support mem+swap controller. But this is still under test and the series is not well organised. and base tree is old. (2.6.27-rc1-mm1) I'll rebase this set to newer mmtom tree. Maybe this set have some troubles/objections but I think the direction is not bad. Patch description. (patch ordering is bad. I'll fix in the next post.) [1/9] ... private_counter ...replace res_counter with my own counter. This is for supporting mem+swap controller. (And I think memcg has a bit different characteristics from other users of res_counter....) [2/9] ... change-order-uncharge ... This patch is for making it easy to handle swap-cache. [3/9] ... atomic_flags This patch changes operations for page_cgroup->flags to be atomic_ops. [4/9] ... delayed freeing. delaying to free page_cgroup at uncharge. [5/9] ... RCU freeing of page_cgroup free page_cgroup by RCU. [6/9] ... lockress page cgroup. remove lock_page_cgroup() and use RCU semantics. [7/9] ... add preftech add prefetch() macro [8/9] ... mem+swap controller base. introduce mem+swap controller. A bit big patch....but have tons of TODO. and have troubles. (it seems it's difficult to cause OOM killer.) [9/9] ... mem+swap controller control files. add mem+swap controller's control files. I'd like to push patch [2,3,4,5,6,7] first.
