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.
