Nick, this is one reason why you were banned from all vger.kernel.org mailing lists. You are wasting people's time and refuse to listen to others. I do give you credit for coming up with very strange questions that show a complete lack of understanding of the C language, that is intertaining at times, like this response, nice job with that. Please everyone, just add him to your killfile and ignore him, it makes life much easier these days when he tries to go around the vger ban by emailing developers directly as he did here. greg k-h _______________________________________________ devel mailing list de...@linuxdriverproject.org http://driverdev.linuxdriverproject.org/mailman/listinfo/driverdev-devel
