Suggest code rework. As I see, linux-kernel is very high volume(noise?) list, may better wil be resend to relevant mantainer(Andrew Morton?) - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
