3.16.84-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Jan Kara <jack@xxxxxxx>
commit 5474ca7da6f34fa95e82edc747d5faa19cbdfb5c upstream.
When a filesystem is mounted with jdev mount option, we store the
journal device name in an allocated string in superblock. However we
fail to ever free that string. Fix it.
