Enable the scsi_dispatch_cmd_start tracepoint using trace-cmd or debugfs, and filter using host_no/channel/id/lun for your specific device. See Documentation/trace/events.txt for details on setting up filters. -- 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
