36# DESCRIPTION:
37#	Verify used is correct.
38#
39# STRATEGY:
40#	1. Create a filesystem.
41#	2. Set refreservation of the filesystem.
42#	3. Make file in the filesystem.
43#	4. Create sub filesystem and make file in it.
44#	5. Create volume under it.
45#	6. Snapshot it.
46#	7. Check used=usedbychildren+usedbydataset+
47#		usedbyrefreservation+usedbysnapshots.
