# DESCRIPTION:
# 'zfs recv -d <fs>' should create ancestor filesystem if it does not
# exist and it should not fail if it exists
#
# STRATEGY:
# 1. Create pool and fs.
# 2. Create some files in fs and take snapshots.
# 3. Keep the stream and restore the stream to the pool
# 4. Verify receiving the stream succeeds, and the ancestor filesystem
# is created if it did not exist
# 5. Verify receiving the stream still succeeds when ancestor filesystem
# exists
#
