Understanding the Linux Kernel: Bovet, Cesati
Posted by Mark on December 14th, 2005
If you are doing any Linux kernel development you need this book. Frankly if you are just using Linux in general this is a good book to have. Certainly not something you want to rip through in one reading, this book covers a wide range of kernel design, interfaces, and internals. And it does so in quite a lot of depth.
