You can only see your own namespace. So e.g. /proc/mtab is your name space's mount table and you can rescan that when receiving the mount signal.
That is sort of the coolness of this approach - push the payload out to user-space, and we don't have to worry about things like information leak, name spaces, security, etc. We are just providing a notify mechanism for state information that should already be exposed through sysfs.
So there is no information leak.
