RFC: 

Can and should we work towards using this as interface for drivers that
need callbacks from an external (closed source) library/HAL?

As I mentioned to Richard Jonson, it can be considered as
ioctl. ioctl-ng!
Unified interface (as ioctl) can be used for any type of modules.
It is just a bit extended ioctl :)

And _yes_, it can be used to turn on/off binary-only callbacks.
Remember pwc - closed part can register callback and open part can
send message, or even closed part can register notification when
open part registers itself and begin to "trash the kernel".

I understand that it is not right way to include it is into the kernel,
but I personally do not understand how it is different 
from just extended ioctl. It was designed to be usefull and convenient,
and it is.

BTW, any binary-only module can _itself_ create netlink socket
with input callback. And that is all - it will be absolutely
the same as above.

One may consider connector as yet-another-netlink-helper.

Eh. I'm just wondering if there's any *right* way of using binary
callbacks on a linux driver so that it doesn't *taint* and possibly
*trash it*, as you said. I was wondering if perhaps through the
connector we could somehow protect the kernel of possibly ill-behaved callbacks.

Comments?
