OK, it seems I was overly optimistic when directing you to existing drivers. Sorry about that I wasn't aware you could find such a terrible code there. Please refer to Linux Device Drivers book which should give you a much better lead (e.g. http://www.makelinux.net/ldd3/chp-15-sect-2) -- Michal Hocko SUSE Labs -- 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/
