Most likely the implementation should just do an open_device_root() like
the other volume functions. However, the corresponding ntdll functions
to retrieve volume information from a file handle are not implemented
yet, so it will be a bit of work.

In any case, if you think the existing tests are not good enough, you
can certainly add more of them to clarify things. But any proposed patch
has to pass the existing tests, plus of course any new ones.
