This is a userspace-visible change, but I guess it's unavoidable. Will anything break? Also, I dislike this approach of duplicating the firmware device tree path in sysfs. Are GX/ibmebus devices guaranteed to be children of the same node in the OF device tree? If so, their unit addresses will be unique, and therefore suitable values for bus_id. I believe this is what the powerpc vio bus code does. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
