Eeeek... Much, _much_ simpler approach would be to have char buf[10]; if (count > 9) return -EINVAL; if (copy_from_user(buf, buffer, count)) return -EFAULT; buf[count] = '\0'; /* use sscanf() or anything normal */ Would that change behaviour in any cases you care about? - 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/
