[PATCH 0/3 RESEND] Per memcg lru_gen node stat

From: Huan Yang

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.

HuanYang (3):
mm: multi-gen LRU: fold lru_gen run cmd
mm: memcg: add per memcg "lru_gen" node
mm: multi-gen LRU: add per memcg "lru_gen" document
