From: Ying Han <yinghan@xxxxxxxxxx>
Subject: memcg: fix up documentation on global LRU
In v3.3-rc1, the global LRU has been removed with commit "mm: make
per-memcg LRU lists exclusive". The patch fixes up the memcg docs.
I left the swap session to someone who has better understanding of
'memory+swap'.
