  36 # DESCRIPTION:
  37 #       Verify usedbydataset is correct.
  38 #
  39 # STRATEGY:
  40 #       1. Create a filesystem.
  41 #       2. Make file in the filesystem.
  42 #       3. Snapshot it.
  43 #       4. Clone it and make file in the cloned filesystem.
  44 #       5. Check usedbydataset is correct.
