-Subject: [PATCH] ext4: don't mark mmp buffer head dirty
-
-Marking mmp bh dirty before writing it will make writeback
-pick up mmp block later and submit a write, we don't want the
-duplicate write as kmmpd thread should have full control of
-reading and writing the mmp block.
-Another reason is we will also have random I/O error on
-the writeback request when blk integrity is enabled, because
-kmmpd could modify the content of the mmp block(e.g. setting
-new seq and time) while the mmp block is under I/O requested
-by writeback.
