  35 # DESCRIPTION:
  36 #       refquotas are not limited by sub-filesystem snapshots.
  37 #
  38 # STRATEGY:
  39 #       1. Setting refquota < quota for parent
  40 #       2. Create file in sub-filesystem, take snapshot and remove the file
  41 #       3. Verify sub-filesystem snapshot will not consume refquota
  42 #
