On original global lru_gen node in debugfs, it can all show each memcg's lru gen info in "lru_gen" or "lru_gen_full", and can type cmd into lru_gen. But which show info contains all memcg's info, and cmd need to know memcg's id. This patchset add lru_gen node in per memcg, with this node, we can get lru_gen info in each memcg. Also, we can type cmd to control each memcg's lru_gen seq, but, this node don't support multi cmd, single memcg just process one cmd once time.
