Sorry for delay-reply because recently I have little free time. Mutex is lightweighter than semaphore, the device/class is used heavily in kernel, so I think the convert would be worth. > > If the latter, I would suggest dropping it, as this area is quite > complex and I think the locking chain too deep at times for a simple > conversion.
