  36 # DESCRIPTION:
  37 #       Verify used is correct.
  38 #
  39 # STRATEGY:
  40 #       1. Create a filesystem.
  41 #       2. Set refreservation of the filesystem.
  42 #       3. Make file in the filesystem.
  43 #       4. Create sub filesystem and make file in it.
  44 #       5. Create volume under it.
  45 #       6. Snapshot it.
  46 #       7. Check used=usedbychildren+usedbydataset+
  47 #               usedbyrefreservation+usedbysnapshots.
