#
# DESCRIPTION:
# If invoke "zfs unmount [-f]" with a filesystem|mountpoint
# whose name is not in "zfs list",
# it will fail with a return code of 1
# and issue an error message.
#
# STRATEGY:
# 1. Make sure that the non-existent ZFS filesystem|mountpoint
# not in 'zfs list'.
# 2. Unmount the file system using the various combinations.
#	- Without force option. (FAILED)
#	- With force option. (FAILED)
# 3. Unmount the mountpoint using the various combinations.
#	- Without force option. (FAILED)
#	- With force option. (FAILED)
# 4. Verify the above expected results of the filesystem|mountpoint.
