    Subject[PATCH 0/7] Per-cgroup page stat accounting
    Date
    This patch series provide the ability for each memory cgroup to have independent
    dirty/writeback page stats. This can provide some information for per-cgroup direct
    reclaim. Meanwhile, we add more detailed dump messages for memcg OOMs.

    Three features are included in this patch series:
    (0).prepare patches for page accounting
    1. memcg dirty page accounting
    2. memcg writeback page accounting
    3. memcg OOMs dump info

    In (0) prepare patches, we have reworked vfs set page dirty routines to make "modify
    page info" and "dirty page accouting" stay in one function as much as possible for
    the sake of memcg bigger lock.

    These patches are cooked based on Andrew's akpm tree.
