The code only differed by the nbpend_max counter. Let's have a pointer to it and merge the two variants to always use a generic queue. It was initially considered to put the max inside the queue structure itself, but the stats support clearing values and maxes and this would have been the only counter having to be handled separately there. Given that we don't need this max anywhere outside stats, let's keep it where it is and have a pointer to it instead. The CAS loop to update the max remains. It was naively thought that it would have been faster without atomic ops inside the lock, but this is not the case for the simple reason that it is a max, it converges very quickly and never has to perform the check anymore. Thus this code is better out of the lock. The queue_idx is still updated inside the lock since that's where the idx is updated, though it could be performed using atomic ops given that it's only used to roughly count places for logging. |
