In the tty layer, as far as I can tell, we have: close races with hangup; open races with everything (other opens, close, hangup, shutdown, remove, ...). Clearly the BKL isn't going to solve all these races, but for many of them it's the only synchronization method being used. It's not clear that things can be fixed by making changes only at the USB level.
