Linux 内核保留有大量的复杂的代码, 但是, 那些想要成为内核 hacker 的人需要一个入口点, 这样他们可以进入代码中, 不会被代码的复杂性压倒. 通常, 设备驱动提供了这样的门路.-To the free Linux operating system represented by one of the many advantages is that they are internal is open to everyone to see. Operating system, was once a hidden and mysterious places, it s code only a limited number of programmers, and now is ready to let anyone have the necessary skills to examine, understand and modify.
