24# DESCRIPTION:
25# Verify that the parent dataset is passed to the kernel's zfs_secpolicy_recv
26# function during a zfs receive.
27#
28# STRATEGY:
29# 1. Create a hierarchy of datasets.
30# 2. Take a snapshot of the final child dataset and send it to a file.
31# 3. Use DTrace to run the zfs recv command and simultaneously monitor the
32#    zc_name member of the zfs_cmd_t structure that is validated in
33#    zfs_secpolicy_recv.
34# 4. Verify that the zc_name member is the parent dataset, as expected.
