btrfs/085 mount and works on $FLAKEY_DEV, but it's inspecting the underlying $SCRATCH_DEV. Since writing to dm-flakey does not invalidate page cache of $SCRATCH_DEV, the btrfs command can read a stalled data from page cache. We should check the flakey device to avoid such cache inconsistency.

# 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
