41# DESCRIPTION:
42#	Verify usedbychildren is correct.
43#
44# STRATEGY:
45#	1. Create a filesystem.
46#	2. Create sub filesystem and make file in it.
47#	3. Set reservation of the sub filesystem.
48#	4. Create volume under it.
49#	5. Snapshot it.
50#	6. Check usedbychildren is correct.
51#
52# TESTABILITY: explicit
53#
54# TEST_AUTOMATION_LEVEL: automated
55#
56# CODING_STATUS: COMPLETED (2009-04-28)
