  • The test always passes OPEN_TREE_CLONE, bug?
  • AT_RECURSIVE is not tested at all

If not pass OPEN_TREE_CLONE flag, then move_mount will return TFAIL: move_mount() failed: EINVAL (22)
It seems move_mount need new namespace otherwise will trigger a error.

In following code "attached" will become 1 and move_mount will go out with failure.
