  36 # DESCRIPTION:
  37 # If invoke "zfs unmount" with a specific filesystem|mountpoint
  38 # that have been mounted, but it's currently in use,
  39 # it will fail with a return code of 1
  40 # and issue an error message.
  41 # But unmount forcefully will bypass this restriction and
  42 # unmount that given filesystem successfully.
  43 #
  44 # STRATEGY:
  45 # 1. Make sure that the ZFS filesystem is mounted.
  46 # 2. Change directory to that given mountpoint.
  47 # 3. Unmount the file system using the various combinations.
  48 #       - Without force option. (FAILED)
  49 #       - With force option. (PASS)
  50 # 4. Unmount the mountpoint using the various combinations.
  51 #       - Without force option. (FAILED)
  52 #       - With force option. (PASS)
  53 # 5. Verify the above expected results of the filesystem|mountpoint.
