Update the remaining calls to 'btrfs' that use shortened command names. Use of full names is recommended to avoid any ambiguities. Signed-off-by: David Sterba <dsterba@suse.com> Reviewed-by: Eryu Guan <eguan@redhat.com> Signed-off-by: Eryu Guan <eguan@redhat.com>

# Tests to ensure that orphan items are properly created and cleaned up
|
|
# on next mount.
|
|
#
|
|
# There are three cases where orphan items may be cleaned up:
|
|
# 1) Default subvolume is fs tree root (mkfs default)
|
|
# 2) Default subvolume is explicitly created subvolume
|
|
# (i.e. btrfs subvol set-default)
|
|
# 3) Non-default subvolume lookup
|
