# DESCRIPTION:
# refquota limits the amount of space a dataset can consume, but does
# not include space used by descendents.
#
# STRATEGY:
# 1. Setting refquota in given filesystem
# 2. Create descendent filesystem
# 3. Verify refquota limits the amount of space a dataset can consume
# 4. Verify the limit does not impact descendents
