+ if (ret) + goto out; + bio = req->bio;I think we can also do away with this bio local variable now.+ if (bdev) + bio_set_dev(bio, bdev);We don't need the bio_set_dev here as mentioned last time, so I think we should remove it in a prep patch.
we miss completing polled io with this change. bdev needs to be put in bio to complete polled passthrough IO. nvme_ns_chr_uring_cmd_iopoll uses bio_poll and that in turn makes use of this.
