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
