Summary: One of the very best technical books I own
Review: I buy a lot of technical books - more than I could possibly ever read. This title is, for me, very readable. The Author presents information the way I want to see it. I really like the historical background information on Linux and comparisons to Unix. If you are looking for one single reference on Linux programming, I recommend this title. Not just for kernel hacking.

Summary: Excellent Linux kernel development book for newbie and prof.
Review: I have been doing Linux kernel/system level development on and off since 1999. This is the book that I think should be owned by any Linux newbie who wants starting their kernel hacking. Even if people do not directly do Linux kernel development, it is a good book complementary to any serious operating systems course in college - it helps gain a better idea of how and why.
The book is quite easy to follow and read and does not try to overwhelm readers with tons of information (consequently it does not address many details in Linux kernel). I consider this is a major strength of the book which parts away from other books (comparing to "Understanding the Linux Kernel", which has quite some details on each subsystem, but if you take the book as your guide to kernel programming, you feel you are overwhelmed by the information and often clueless on where to start to write some simple stuffs. This does not mean I think the latter is a bad one - it is a very good one indeed). Considering the fact that Linux kernel evolves so fast, it may make sense to focus on the core parts and once you understand them, it may become easy for you to track and understand changes later. Even as a professional programmer doing kernel development, occasionally referencing a well-written book like this is very helpful.
I am a bit reluctant to rate it 5 stars though due to many typos observed, which I guess is the result of rush to publishing (and the poor job of proofreading). Fortuanately, most can be understood by reading the contexts around them. But a few are really misleading or totally wrong. For example, on page 169, there is a sample code to show how page allocation/free is done in kernel. It uses __get_free_pages() to allocate pages, but uses free_pages() to free these pages. As the author has just said a page ago, __free_pages() should be used to free (struct page*) pages, otherwise corruption will ensure (free_pages is used to free pages with logic address as parameter).

Summary: 496 Pages. I think not.
Review: I just got the book today. I feel deceived in that the details about this book stated around 500 pages. Given the price, I figured this was a reasonable price/page ratio. Now that I have the book in hand, I realize it's only 330 pages, including index and stuff.I guess this is more of a beef with Amazon than the book.

Summary: Great book
Review: I like the book because it is well organized, clear, no nonsense, explains the subject top-down, up-to-date including kernel 2.6, contains very little code and despite the subject still readable as a regular book. It is like a book about operating systems in general but about Linux only. I'd recommend reading this book before "Understanding the Linux Kernel".
However, I find the word "Development" in the title a little misleading because the book contains very little about the actual howto and could have been backed up by for example an appendix with an example from real life with a step-by-step walk-thru by the hand.

Summary: clear and careful explanations from an expert
Review: I was a Linux kernel newbie writing a device driver and started reading "Linux Device Drivers" by Rubini. On hindsight, this was a bad idea. Rubini's book goes deep into driver code quickly with good details but it only sparingly touches the higher level kernel overview or essential concepts. These missing pieces are covered very well in Love's book and I should have understood them before reading Rubini's book; important basic concepts covered in good detail include: - user thread vs kernel thread.
- kernel-space process context vs kernel-space interrupt context.
- tasklet as a non-concurrent form of softirq and is not related in any way to tasks.
- bottom-half methods comprising softirq, tasklet and work queue; and that BH and task queue are obsolete and deprecated.
- semaphore sleeping vs spinlock spinning (busy-wait).
- spinlock adversely affecting scheduling latency while semaphore does not. Love's book shows ambly that he is an expert in Linux kernel matters and speaks with authority. At the same time he has the ability of a good teacher to explain obscure and critical kernel concepts clearly. I heartily recommend this as the first book one should read about the Linux kernel, well before books such as Bovet's "Understanding the Linux Kernel" or Rubini's device driver book.

Summary: Superb
Review: Just bought it from amazon. After two days reading many of my doubts on the Linux Kernel were solved and I must say this book has a great structure and good editorial work on it! A very good Book.

Summary: A must read book for kernel developpers
Review: The author is really a good teacher. He gradually takes the reader into the dark woods of kernel and still assures the ease of understanding the programming concepts well.You really feel the joy of evolving into a professional as you read this book.Kudos.
I own it.

Summary: A Great Book on the kernel... with a sense of humor.
Review: There are more technical books than Linux Kernel Development, with more code samples and technical jargon, but when it comes to up to date knowledge, and a clear, concise writing style, this volume is one of the best. Robert Love has written a book that is readable for both kernel newbies and those wishing to get a better grasp for what is at the heart of 2.6. However, what I find most appealing about this book is it has a sense of humor that most other technical books seem to have left at home. This is a book you will read cover to cover, instead of using it as a meer reference. I recommend this book to anyone who wants to learn, or brush up on, the linux kernel.

Summary: good book on Linux 2.6 kernel programming
Review: There are not many good books on Linux kernel programming. This is the most recent good book. The text is informative, but there are quite a few typos. "Linux Device Drivers" is another good book on Linux kernel programmaing, but it focuses on the older Linux 2.4.
