ext2: Remove s_dirt handling
Places which modify superblock feature / state fields mark the superblock buffer dirty so it is written out by flusher thread. Thus there's no need to set s_dirt there. The only other fields changing in the superblock are the numbers of free blocks, free inodes and s_wtime. There's no real need to write (or even compute) these periodically. Free blocks / inodes counters are recomputed on every mount from group counters anyway and value of s_wtime is only informational and imprecise anyway. So it should be enough to write these opportunistically on mount, remount, umount, and sync_fs times. Signed-off-by: Jan Kara <jack@suse.cz>
