# DESCRIPTION:
# Verify that the parent dataset is passed to the kernel's zfs_secpolicy_recv
# function during a zfs receive.
#
# STRATEGY:
# 1. Create a hierarchy of datasets.
# 2. Take a snapshot of the final child dataset and send it to a file.
# 3. Use DTrace to run the zfs recv command and simultaneously monitor the
# zc_name member of the zfs_cmd_t structure that is validated in
# zfs_secpolicy_recv.
# 4. Verify that the zc_name member is the parent dataset, as expected.
