It looks like the answer is probably “no”, which is good. mount_notify(). You can get a notification that someone altered the mount topology (eg. by mounting something). A process receiving a notification could then use fsinfo(), say, to reread the mount topology tree, find out where the new mount is and wander over there to have a look - assuming they have the permissions for pathwalk to succeed.
