SCSI allocates the request_queue using the normal blk_mq_init_queue function in scsi_alloc_sdev. It it then used to send SCSI passthrough commands for probing before eventually binding an upper level driver using the driver model (or something not binding one at all if there is none for the device type). _______________________________________________ Linux-nvme mailing list Linux-nvme@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-nvme
