35# DESCRIPTION:
36# Setting readonly on a dataset, it should keep the dataset as readonly.
37#
38# STRATEGY:
39# 1. Create pool, then create filesystem and volume within it.
40# 2. Setting readonly to each dataset.
41# 3. Check the return value and make sure it is 0.
42# 4. Verify the stuff under mountpoint is readonly.
