[PATCH 0/2] Use up free swap space before reaching OOM kill

[Minchan Kim]

Recently, Luigi reported there are lots of free swap space when
OOM happens. It's easily reproduced on zram-over-swap, where
many instance of memory hogs are running and laptop_mode = 2.

This patchset fixes the problem. In fact, if we apply one of two,
we can fix the problem but I send two all because it's separate
issue although each of them solves this issues.

Andrew, Could you replace [1] with this patchset in mmotm?
I think this patchset is better than [1].

[1] mm-swap-out-anonymous-page-regardless-of-laptop_mode.patch

Minchan Kim (2):
  [1/2] mm: prevent to add a page to swap if may_writepage is unset
  [2/2] mm: forcely swapout when we are out of page cache
