The queueing function is really in the best position to do this. It knows the size of each request. However in the cleanup/status check routine, all we know is the last request completed -- we don't know the completed requests' sizes. The other reason is that the DMA engine should never throw an error. If it does then something is very wrong, we print scary warnings, and up-to-date stats are the least of our problems.
