# DESCRIPTION:
# Setting readonly on a dataset, it should keep the dataset as readonly.
#
# STRATEGY:
# 1. Create pool, then create filesystem and volume within it.
# 2. Setting readonly to each dataset.
# 3. Check the return value and make sure it is 0.
# 4. Verify the stuff under mountpoint is readonly.
