Hello, Are the scsi_device structures actually the same one in sd and sg driver? It seems that the scsi_device structure in sg come from class_device in sg_add function. And the scsi_device structure in sd when driver loading, ie. when scsi_scan_host or sd_probe. So, are they the same structure in memory(ie, they have the same request queue) ?
