Before I start, I guess I've got two questions: 1. Is anybody else doing this. 2. Given that I'll need to change the d_open prototype (and thus cdevsw), I'm going to affect every device driver in the tree - although only changing the first arg to a (dev_t) pointer, making things pretty easy to change and not too unexpected for anyone that's written sysv drivers. Is it acceptable to simply not support old drivers ? I've considered trying to do things so that they're backwards compatible, but I think the answer is that it'd be too much of a crutch in the future. Ok, ok, three questions ! 3. Should I ask for review anywhere else besides here ? Ta. -- Brian Don't _EVER_ lose your sense of humour !
