36# DESCRIPTION:
37#	Verify usedbychildren is correct.
38#
39# STRATEGY:
40#	1. Create a filesystem.
41#	2. Create sub filesystem and make file in it.
42#	3. Set reservation of the sub filesystem.
43#	4. Create volume under it.
44#	5. Snapshot it.
45#	6. Check usedbychildren is correct.
46#
47# TESTABILITY: explicit
48#
49# TEST_AUTOMATION_LEVEL: automated
50#
51# CODING_STATUS: COMPLETED (2009-04-28)
