btrfs-progs: subvol show: print more details about toplevel subvolume
The toplevel subvolume is special and the other listing code leaves it out so we have to add several special cases to handle it. There's no backreference so the path is built artificially. New helper btrfs_get_toplevel_subvol is a reduced version of btrfs_get_subvol. There's some information usually missing for the toplevel subvolume, eg. the uuid or creation info. This has to be fixed on the mkfs side, the other subvolumes are created by kernel. Example: /mnt Name: <FS_TREE> UUID: - Parent UUID: - Received UUID: - Creation time: - Subvolume ID: 5 Generation: 233 Gen at creation: 0 Parent ID: 0 Top level ID: 0 Flags: - Snapshot(s): subv1 Signed-off-by: David Sterba <dsterba@suse.com>
