I did report the author here ^^, I didn't see a reported by credit on the 
original email.

and I suggested this was the patch, and I was wrong, and I've rewritten 
it, and not I realise the drm ioctls are as ever a really big mess, the 
driver ioctls on the kernel side don't have direction bits which is really 
bad.
