  36 # DESCRIPTION:
  37 # Invoke "zfs mount <filesystem>" with a filesystem but its mountpoint
  38 # is currently in use.  Under Linux this should succeed and is the
  39 # expected behavior, it will fail with a return code of 1 and issue
  40 # an error message on other platforms.
  41 #
  42 # STRATEGY:
  43 # 1. Make sure that the ZFS filesystem is unmounted.
  44 # 2. Apply 'zfs set mountpoint=path <filesystem>'.
  45 # 3. Change directory to that given mountpoint.
  46 # 3. Invoke 'zfs mount <filesystem>'.
  47 # 4. Verify that mount succeeds on Linux and fails for other platforms.
