Subject: memcg-remove-the-overhead-associated-with-the-root-cgroup-fix-2
From: Balbir Singh <balbir@xxxxxxxxxxxxxxxxxx>
Fix an incorrect condition in memcg lru manipulation
The PageAcctLRU bit itself does not mean a lot without checking
if the mem cgroup is the same as the root cgroup. This patch
fixes a left over from the previous versions.
