This is version 5 of the memcg naturalization patches. They enable traditional page reclaim to find pages from the per-memcg LRU lists, thereby getting rid of the double-LRU scheme (per global zone in addition to per memcg-zone) and the required extra list head per each page in the system. The only change from version 4 is using the name `memcg' instead of `mem' for memcg pointers in code added in the series. This series is based on v3.2-rc1. memcg users and distributions are waiting for this because of the memory savings. The changes for regular users that do not create memcgs in addition to the root memcg are minimal, and even smaller for users that disable the memcg feature at compile time. Lastly, ongoing memcg development, like the breaking up of zone->lru_lock, fixing the soft limit implementation/memory guarantees and per-memcg reclaim statistics, is already based on this.
