In the catchall case both vf->bus and vf->pf->bus will have the same domain (segment) regardless of whether we have large VF count or big offset/stride. So, I suppose this could be done inside of dmar_pci_device_match(). Otherwise, I think you'd want to add the same thing to dmar_find_matched_atsr_unit() since it's the same device scopes there. thanks, -chris -- To unsubscribe from this list: send the line "unsubscribe linux-pci" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
