Christoph Hellwig cf37e97247 writeback: enforce s_umount locking in writeback_inodes_sb
Make sure that not only sync_filesystem but all callers of writeback_inodes_sb
have the superblock protected against remount.  As-is this disables all
functionality for these callers, but the next patch relies on this locking to
fix writeback_inodes_sb for sync_filesystem.
