Hi,
I'm considering having a crack at adding support for cloned opens.
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.
