[PATCH 0/2] Avoid unnecessary overhead in fault paths due to memcg and rss stats

[Mel Gorman]

While looking for something else entirely I spotted two small issues in the
page fault fast path. Enabling memcg takes the RCU read lock unnecessarily
even when the task is not part of a memcg and we fiddle with RSS stats
more than necessary. Details in the patches.
