I dislike this patch, because I don't see any reason why logic specific to per memcg reclaim should live in the file representing the global reclaim path. With such an approach you may end up with moving mem_cgroup_low, mem_cgroup_soft_limit_reclaim, etc to vmscan.c, because they are used only there. I don't think it's right.
