ext2: write superblock only once on unmount
Currently on unmount if we are mounted R/W, we first write the superblock to the media if it is dirty, and then write it again, which is not optimal. This patch makes ext2 write the superblock on unmount less times. Signed-off-by: Artem Bityutskiy <artem.bityutskiy@linux.intel.com> Signed-off-by: Jan Kara <jack@suse.cz>
