That should correct the SCSI layer assumptions. I don't get it. First in scsi_alloc_queue, the flush/sync code is only used if we don't have ordered tags, and if the adapter driver explicitly allows it (shost->order_flush). Plus we clear order_flush in scsi_host_alloc if can_queue > 1. So ipr will never get those sync cache commands, correct? And we default to QUEUE_ORDERED_NONE (0) if ordered_tag and ordered_flush are not set. But I can't find any where that we set ordered_tag at all, am I missing something??? Let alone in ipr. -- Patrick Mansfield - : 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
