One doubt here. This patch has put NvmeRequest argument to the nvme_map_prp() to trace the request's command id. But can we just trace the cid before this kind of prp mapping, somewhere like nvme_process_sq() level. Then we can figure out the tracing for the prp mapping is from which request. Tracing for cid is definitely great, but feels like too much cost to pass argument to trace 'cid' in the middle of the dma mapping stage. Thanks,
