No ref counting, no tty port, no compliance with the tty behaviour. Concept looks fine but it needs porting to reflect a kernel newer than about 2.6.18 8) I would take a quick look at the tty_port helpers and also check v -next which makes the tty_port mandatory. That'll pretty much cover your needs for locking, semantics and the like.
