No I worded that badly - the direction isn't useless, but thinking of it in terms of a buffer property rather than data movement is inaccurate. So then if we need something else to indicate how data was expected to be moved, the direction argument becomes useless, since it's not a buffer property but rather a temporal thing on a specific place that expected certain data movement. johannes _______________________________________________ iommu mailing list [email protected] https://lists.linuxfoundation.org/mailman/listinfo/iommu
