He's saying that even if you happen to know where it's currently
mounted, there's no guarantee the place where it's mounted might not be
changed without your filesystem knowing. Indeed, it can be mounted
nowhere at all (and yet still active) or it can be mounted in 2 or more
places at the same time. What you've told us you're trying to do is
impossible.

No way at all. What are you actually trying to do?
