  33 # When using 'zfs destroy -R' on a file system hierarchy that includes a
  34 # snapshot and a clone of that snapshot, and the snapshot has been
  35 # defer-destroyed, make sure that the 'zfs destroy -R' works as expected.
  36 # In particular make sure that libzfs is not confused by the fact that the
  37 # kernel will automatically remove the defer-destroyed snapshot when the
  38 # clone is destroyed.
  39 #
  40 # 1. Create test environment.
  41 # 2. Create a clone of the snapshot.
  42 # 3. 'zfs destroy -d <snap>'
  43 # 4. 'zfs destroy -R'
  44 # 5. Verify that the snapshot and clone are destroyed.
