  35 # DESCRIPTION:
  36 #       refquota limits the amount of space a dataset can consume, but does
  37 #       not include space used by descendents.
  38 #
  39 # STRATEGY:
  40 #       1. Setting refquota in given filesystem
  41 #       2. Create descendent filesystem
  42 #       3. Verify refquota limits the amount of space a dataset can consume
  43 #       4. Verify the limit does not impact descendents
  44 #
