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