#
# When using 'zfs destroy -R' on a file system heirarchy that inclues 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.
