It feels very much ad-hoc, with most references to ->sem being unbalanced. The driver has a thread (airo_thread) and it seems to be trying to synchronise against both the interrupt handler, and other threads (calling eg ->get_stats). I think it really wants to be using spin_lock_irqsave() instead of a mutex. I'd want to study the driver in a lot more detail before making that kind of change though. -- Intel are signing my paycheques ... these opinions are still mine "Bill, look, we understand that you're interested in selling us this operating system, but compare it to ours.
