+# DESCRIPTION:
+# "zfs unmount -u" should allow the user to unload their encryption
+# keys while unmounting one or more datasets
+#
+# STRATEGY:
+# 1. Create a hierarchy of encrypted datasets
+# 2. Test that 'zfs unmount -u' unloads keys as it unmounts a dataset
+# 3. Test that 'zfs unmount -u' unloads keys as it unmounts multiple datasets
+# 4. Test that 'zfs unmount -u' returns an error if the key is still in
+#    use by a clone.
