# DESCRIPTION:
#	User defined property are always inherited from its parent dataset
#	directly.
#
# STRATEGY:
#	1. Create pool, fs, volume, fsclone & volclone.
#	2. Get random user property name and set to the pool
#	3. Verify all dataset user property inherit from pool.
#	4. Set intermediate dataset and verify its children will inherit user
#	   property from it directly.
