25# DESCRIPTION:
26# 'zfs unload-key -r' should recursively unload keys.
27#
28# STRATEGY:
29# 1. Create a parent encrypted dataset
30# 2. Create a sibling encrypted dataset
31# 3. Create a child dataset as an encryption root
32# 4. Unmount all datasets
33# 5. Attempt to unload all dataset keys under parent
34# 6. Verify parent and child have their keys unloaded
35# 7. Verify sibling has its key loaded
36# 8. Attempt to mount all datasets
