# ID: refquota_003_pos
#
# DESCRIPTION:
#	Sub-filesystem quotas are not enforced by property 'refquota'
#
# STRATEGY:
#	1. Setting quota and refquota for parent. refquota < quota
#	2. Verify sub-filesystem will not be limited by refquota
#	3. Verify sub-filesystem will only be limited by quota
#
# TESTABILITY: explicit
#
# TEST_AUTOMATION_LEVEL: automated
#
# CODING_STATUS: COMPLETED (2007-11-02)
