因为本人现在也在做OS的工作,需要大量学习Linux的相关实现,想请教一下除了直接阅读源码之外是怎么学习 Linux 中某个模块的实现的,或者说有什么比较高效的阅读源码的技巧?还有如此翔实的历史变更是从哪里学习的,还请不吝赐教
linux kernel 3.10 module 没有 mod->refcnt
只有
struct module_ref __percpu *refptr;
struct module_ref {
unsigned long incs;
unsigned long decs;
}
请问这个如何将cpu的各个module的refptr 设置为0?
另外在kernel空间如何强制终止一个进程呢?
非常感谢
无敌哥,请教能否测试体验提供下意见

其中在解释高端内存时有一句:
因此x86架构中将内核地址空间划分三部分:
我觉得因为是:内核将物理地址空间划分为三部分,而不是将内核地址空间。

最近在读《深入理解Linux内核》。想进行实际调试下。不知道现在最新,或者最高效的方法是什么。
