摘要:Linux Kernel Development details the design and implementation of the Linux kernel, presenting the content in a manner that is beneficial to those writing and developing kernel code. While the book discusses topics that are theoretical, it does so with the goal of assisting programmers so they better understand the topics and become more efficient and productive in their coding. The book discusses the major subsystems and features of the Linux kernel, including design and implementation, their purpose and goals, and their interfaces. Important computer science and operating system design details are also addressed. The book covers the Linux kernel from both angles - theoretical and applied - which should appeal to both types of readers. The author is involved in Linux kernel development, so the latest kernel version is detailed, as the author has access to the not-yet-released development releases. Specific topics covered will include: all the important algorithms, relevant subsystems, process management, scheduling, time management and timers, system call interface, memory addressing, memory management, paging strategies, caching layers, VFS, kernel synchronization, and signals.
