Hannes just spotted this: static int nvme_queue_rq(struct blk_mq_hw_ctx *hctx, const struct blk_mq_queue_data *bd) { [...] __nvme_submit_cmd(nvmeq, &cmnd); nvme_process_cq(nvmeq); spin_unlock_irq(&nvmeq->q_lock); return BLK_MQ_RQ_QUEUE_OK; out_cleanup_iod: nvme_free_iod(dev, req); out_free_cmd: nvme_cleanup_cmd(req); return ret; }So we're draining the CQ on submit. This of cause makes polling for completions in the IRQ handler rather pointless as we already did in the submission path.
