Sorry, I don't quite understand your meaning. Do you mean I'd better
change this:
trace_nvme_sq(req->rq_disk,
nvmeq->qid,
le16_to_cpu(cqe->sq_head),
nvmeq->sq_tail);
to something like below:
trace_nvme_sq(req->rq_disk, nvmeq->qid, le16_to_cpu(cqe->sq_head),
nvmeq->sq_tail);
Please let me know whether my understanding is correct.
