Daisuke Nishimura 152c9ccb75 thp: transhuge-memcg: commit tail pages at charge ... By this patch, when a transparent hugepage is charged, not only the head page but also all the tail pages are committed, IOW pc->mem_cgroup and pc->flags of tail pages are set. Without this patch: - Tail pages are not linked to any memcg's LRU at splitting. This causes many problems, for example, the charged memcg's directory can never be rmdir'ed because it doesn't have enough pages to scan to make the usage decrease to 0. - "rss" field in memory.stat would be incorrect. Moreover, usage_in_bytes in root cgroup is calculated by the stat not by res_counter(since 2.6.32), it would be incorrect too.
