如何阅读linux OS kernel源代码
如何阅读linux kernel的source code？在拿起本书的时候我思考了这个问题，下面是我检索到的我觉得有道理的观点：
Focus on data structures. Understanding data structures is usually more important than code.
If you are only shown data structures but no code, you still get the big picture of the system.
Vice versa, if shown only code but not data structures, it's very hard to understand the system.
"I will, in fact, claim that the difference between a bad programmer and a good one is whether he considers his code or his data structures more important. Bad programmers worry about the code. Good programmers worry about data structures and their relationships." -- Linus Torvalds
"Show me your flowcharts and conceal your tables, and I shall continue to be mystified. Show me your tables, and I won't usually need your flowcharts; they'll be obvious." -- Fred Brooks.

从structure入手，本书也是如此。
本章会给出阅读Linux OS kernel源码的指导，并对Linux OS kernel源码中的一些重要的data structure进行总结。
