Instead of sending the uid corresponding to the owner of files on the mount, instead send the real uid of the process that initiated the upcall. Usually this will be the real uid of the process running /bin/mount. Eventually however, we want to be able to establish new sessions for users that walk into a cifs mount. For that we need the real uid of those users.
