AF_UNIX passes file handles just fine. I'm not sure netlink will help you
here anyway - isn't it lossy under load ?

Also securityfs is more special purpose magic here - what does it have to
do with a general purpose notifier API ? I'd actually generalise the
notifier properly and go for a syscall.
