Sometimes the style can be a little cheesy and Robert Love avoids many of the device driver issues that most wannabe kernel hackers will face, but as a general and practical introduction to the 2.6 series kernel I doubt this book will be surpassed. Love focuses on the big picture throughout and assumes some, but not too much, general knowledge of operating systems basics. If you want to become a kernel hacker then you need to buy and read this book - I came at all of this the other way round (wrote a device driver and then looked for more about the kernel) - but reading this first would have been better.

This book esplains the Linux kernel internals. It is a mix between a book about Operating Systems, and a book about Linux internals. Every part is initially explained from a theoretical point of view, then the book shows how that part is implemented in the Linux kernel.
If you want to start hacking the kernel, this may not be the right book to start with. At least, you should read also "Linux Device Drivers" to have a more complete vision about how to make Linux do what you want.
Instead, if you want to understand how things work inside Linux, and how start collaborating with the kernel community, then this is the right book.
Unfortunately, the mechanisms inside Linux change very quickly. For this reason, this version (i.e., second) of the book might be too old. For instance, it does not contain the latest (i.e., CFS) Linux scheduler. You should buy the third edition, which, in my point of view, is a minor update of this book, adding some information about the new CFS scheduler and about some new synchronization mechanisms.

I got this book to learn more about operating systems and Linux.
It's ok, quite good even, but for me, a far better book is "Lions' Commentary on UNIX 6 Editition with Source Code". It's much older, but it walks you through the real code of a operating system that started it all.
