Right, but that makes it useless for things which want to open it

For my purposes, if I'm going to emulate pioctl() in userspace, I also need to
be able to open device files that don't have drivers available, and when you
do open a dev file in this manner, it must _not_ call the ->open() routine of
the device driver
So how are you going to make that work in conjunction with the in
progress work on doing stuff like revoke(), and with module reference
counting ?
