#
# DESCRIPTION:
#	Verify 'zpool trim -d' secure trim.
#
# STRATEGY:
#	1. Create a pool on a single file vdev.
#	2. Run 'zpool trim -d' to securely TRIM allocated space maps.
#	3. Verify it fails when using a file vdev.
#
# NOTE: Currently secure discard cannot be verified using file vdevs,
# loopback, or scsi_debug devices.  None of which support the feature.
# It can only be tested using real SSDs which provide support.
