Meanwhile I've submitted a patch to xfs to allow reclaim from kswapd, and just prevent it from direct and memcg reclaim. Btw, it might be worth to also allow kswap to all writeout on ext4, but doing that will be a bit more complicated than the btrfs and xfs variants as the code is rather convoluted. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
