If we run an old tool on a new kernel, or a new tool on an old kernel, does it work properly?
Tools repo carries a copy of the header and thats how the old tool and new tools have been running with older/newer kernels. There are few more bits left before I can start using directly kernel header for newer tools. Moreover this particular parameter is only used for verbose mode which isn't used in default options.
