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 mm/vmscan.c | 8 ++++++++ 1 file changed, 8 insertions(+) -- 1.7.9.5 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
