I don't think adding UAPI to an individual device driver like this is a good approach especially considering that the virtio changes we discussed some time ago will likely augment this and create another means of a similar notification. And given that this intersects with other userspace-oriented work I hope to get back to pretty soon, I think introducing some adhoc mechanism like this adds clutter and isn't the ideal way forward. On top of that, your extremely aggressive approach and apparent disregard for established processes and general sneakiness doesn't really earn you a lot of points here. There wasn't even an iota of recognition in your reply that you realize the way you've gone about this is not fine. That doesn't really sit too well, you know?
