That's only supported for NVMe 1.1 and higher devices, and optional. For older or stupid devices we need to support the algorithm based on the serial attribute from nvme_fill_device_id_scsi_string() in drivers/nvme/host/scsi.c. Which btw is Ń–ncorrect as it doesn't identify namespaces properly, and thus the associatation of 0 is an actively harmful lie. -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
