Like MODE SENSE ;-) I see that two drivers have very different objectives but if we add use_thread option to scsi_debug (we can do easily), it seems that scsi_debug can provide all the features that scsi_ram does. If we clean up scsi_debug driver, can scsi_debug work as a nice scsi ram driver? - To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
