Linus的代码品味之一

本文来自： 视频《TED演讲集：敬畏网络》

品味：重写代码，排除特例，覆盖所有情况

差品味：

remove_list_entry(entry){prev = NULL;walk = head;while (walk != entry){pre = walk;walk = walk->next;}if (!prev)head = entry->next;elseprev->next = entry;}

好品味：

remove_list_entry(entry){indirect = &head;while ((*indirect) != entry)indirect = &(*indirect)->next;*indirect = entry->next;}
