The commit 344150999b7f ("f2fs: fix to avoid potential deadlock") only
requires unplugging current->plug. Using blk_finish_plug() is unnecessary
as it sets current->plug as NULL and prevents wb_writeback() from using
plug in subsequent loops. Instead, use blk_flush_plug() as a replacement.

Yes. Sorry that I miss it. I have sent another patch with this.
Thanks.
