Subject: memcg: lru scan fix
From: KAMEZAWA Hiroyuki <kamezawa.hiroyu@xxxxxxxxxxxxxx>
Since rc5-mm3, memcg easily goes into OOM when limit was low. This is a
fix to split-lru to fix OOM.
Under memcg, active anon tend not to go to inactive anon. This will cause
OOM in memcg easily when tons of anon was used at once. This check was
lacked in split-lru.
