Currently, the top-level subvolume lacks the UUID. As a result, both non-snapshot subvolume and snapshot of top-level subvolume do not have Parent UUID and cannot be distinguisued. Therefore "fi show" of top-level lists all the subvolumes which lacks the UUID in "Snapshot(s)" filed. Also, it lacks the otime information. Fix this by adding the UUID and otime at the mkfs time. As a consequence, snapshots of top-level subvolume now have a Parent UUID and UUID tree will create an entry for top-level subvolume at mount time. This should not cause the problem for current kernel, but user program which relies on the empty Parent UUID may be affected by this change.
