  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.
