Hi, this is a second version of the per-cpu carge draining code cleanup. I have dropped the "fix unnecessary reclaim if there are still cached charges" part because it seems to have some issues and it is not critical at the moment. I think that the cleanup has some sense on its own. Changes since v1: - memcg: do not try to drain per-cpu caches without pages uses drain_cache_local for the current CPU - added memcg: add mem_cgroup_same_or_subtree helper - dropped "memcg: prevent from reclaiming if there are per-cpu cached charges" patch Michal Hocko (4): memcg: do not try to drain per-cpu caches without pages memcg: unify sync and async per-cpu charge cache draining memcg: add mem_cgroup_same_or_subtree helper memcg: get rid of percpu_charge_mutex lock mm/memcontrol.c | 110 +++++++++++++++++++++++++++++++------------------------ 1 files changed, 62 insertions(+), 48 deletions(-) -- 1.7.5.4 -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
