Subject: [PATCH 3/5] f2fs: blk_finish_plug of submit_bio in lfs mode
Date:   Thu, 12 Jul 2018 23:09:28 +0800
Message-ID: <1531408170-45758-4-git-send-email-yunlong.song@huawei.com>

Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Expand the blk_finish_plug action from blkzoned to normal lfs mode,
since plug will cause the out-of-order IO submission, which is not
friendly to flash in lfs mode.
