34#
35# DESCRIPTION:
36#	refquotas are not limited by sub-filesystem snapshots.
37#
38# STRATEGY:
39#	1. Setting refquota < quota for parent
40#	2. Create file in sub-filesytem, take snapshot and remove the file
41#	3. Verify sub-filesystem snapshot will not consume refquota
42#
43# TESTABILITY: explicit
44#
45# TEST_AUTOMATION_LEVEL: automated
46#
47# CODING_STATUS: COMPLETED (2007-11-02)
