xfs: flush dirty data and drain directios before scrubbing cow fork
When we're scrubbing the COW fork, we need to take MMAPLOCK_EXCL to prevent page_mkwrite from modifying any inode state. The ILOCK should suffice to avoid confusing online fsck, but let's take the same locks that we do everywhere else. Signed-off-by: Darrick J.
