#
# DESCRIPTION:
# If invoke "zfs unmount" with a specific filesystem|mountpoint
# that have been mounted, but it's currently in use,
# it will fail with a return code of 1
# and issue an error message.
# But unmount forcefully will bypass this restriction and
# unmount that given filesystem successfully.
#
# STRATEGY:
# 1. Make sure that the ZFS filesystem is mounted.
# 2. Change directory to that given mountpoint.
# 3. Unmount the file system using the various combinations.
#   - Without force option. (FAILED)
#   - With force option. (PASS)
# 4. Unmount the mountpoint using the various combinations.
#   - Without force option. (FAILED)
#   - With force option. (PASS)
# 5. Verify the above expected results of the filesystem|mountpoint.
