Johannes Weiner 7c5bd705d8 mm: memcg: only evict file pages when we have plenty
Commit e986850598 ("mm, vmscan: only evict file pages when we have
plenty") makes a point of not going for anonymous memory while there is
still enough inactive cache around.

The check was added only for global reclaim, but it is just as useful to
reduce swapping in memory cgroup reclaim:
