Subject: f2fs: blk_finish_plug of submit_bio in lfs mode
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=66415cee3d341b19eb2766c118cb5f6fddda077c;p=linux.git

f2fs: blk_finish_plug of submit_bio in lfs mode

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.
