Currently, try_to_unmap returns various return value(SWAP_SUCCESS, SWAP_FAIL, SWAP_AGAIN, SWAP_DIRTY and SWAP_MLOCK). When I look into that, it's unncessary complicated so this patch aims for cleaning it up. Change ttu to boolean function so we can remove SWAP_AGAIN, SWAP_DIRTY, SWAP_MLOCK. * from v1 * add some acked-by * add description about rmap_one's return - Andrew * from RFC - http://lkml.kernel.org/r/1488436765-32350-1-git-send-email-minchan@xxxxxxxxxx * Remove RFC tag * add acked-by to some patches * some of minor fixes * based on mmotm-2017-03-09-16-19.
