21 这个文件是有关当前使用的魔术值注册表。当你给一个结构添加了一个魔术值,你也应该把这个魔术值添加到这个文件,因为我们最好把用于各种结构的魔术值统一起来。
23 使用魔术值来保护内核数据结构是一个非常好的主意。这就允许你在运行期检查(a)一个结构是否已经被攻击,或者(b)你已经给一个例行程序通过了一个错误的结构。后一种情况特别地有用---特别是当你通过一个空指针指向结构体的时候。tty源码,例如,经常通过特定驱动使用这种方法并且反复地排列特定方面的结构。
25 使用魔术值的方法是在结构的开始处声明的,如下:
32 当你以后给内核添加增强功能的时候,请遵守这条规则!这样就会节省数不清的调试时间,特别是一些古怪的情况,例如,数组超出范围并且重新写了超出部分。遵守这个规则,这些情况可以被快速地,安全地避免。
37 给当前的Linux 2.1.55添加魔术表。

43 现在应该最新的Linux 2.1.112.因为在特性冻结期间,不能在2.2.x前改变任何东西。这些条目被数域所排序。

46 <mailto: kgb@knm.org.pl>
49 更新魔术表到Linux 2.5.45。刚好越过特性冻结,但是有可能还会有一些新的魔术值在2.6.x之前融入到内核中。

149 请注意,在声音记忆管理中仍然有一些特殊的为每个驱动定义的魔术值。查看include/sound/sndmagic.h来获取他们完整的列表信息。很多OSS声音驱动拥有自己从声卡PCI ID构建的魔术值-他们也没有被列在这里。
151 IrDA子系统也使用了大量的自己的魔术值,查看include/net/irda/irda.h来获取他们完整的信息。
153 HFS是另外一个比较大的使用魔术值的文件系统-你可以在fs/hfs/hfs.h中找到他们。
