I'm not 100% sure what you mean. There's only one array above. Do you mean that port_guid could be removed ? If so, that's not the case because the p_guids array is only allocated when alias GUIDs are being used which is not the common case. > I guess port_guid would be always the first element of p_guids[]. Yes, port_guid will also be present at index 0 of p_guids array when the p_guids array is allocated. -- Hal > > -- Alex > -- -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
