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. http://marc.info/?l=linux-mm&m=135421750914807&w=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
