“如果有这样一本书，既能提纲挈领，为我理顺思绪、指引方向，同时又能照顾小节，阐述细微，帮助我更好更快地理解源码，那该有多好。”说这话的先生虽然针对的是C++，但道出的是研习题源码的人们的共同心声。我们能不能做点儿什么，让学习Linux内核的过程更符合程序员的习惯呢？本书回答了这个问题。本书作者是一个狂热的内核爱好者，所以他的想法自然贴近程序员。
如果你是一名Linux内核爱好者，那么本书提供的材料会让你想在内核层面上做些什么；如果你是一名普通的编程人员，那么对操作系统的透彻理解会拓宽你的编程思路。
本书内容涉及Linux2.6内核，包含许多新特性，如O（1）调度程序、抢占式内核、块I/O层、I/O调度程序等。
本版新增内容
