I was thinking about:
--
err = nvme_rdma_post_send(queue, sqe, req->sge, req->num_sge,
req->mr ? &req->reg_wr.wr : NULL);
if (unlikely(err)) {
if (err == -EIO) {
/*

*/
req->status = NVME_SC_HOST_PATH_ERROR;
nvme_rdma_complete_rq(rq);
return BLK_STS_OK;Need to do clean. so can not directly return.
The completion path cleans up though
ok, i see.
But we need to use the new helper nvme_complete_failed_rq to avoid double request completion.
Or we can do like this:
req->status = NVME_SC_HOST_PATH_ERROR;
blk_mq_set_request_complete(req);
nvme_rdma_complete_rq(rq);

goto err_unmap;
