Cheap Linux Kernel Development (3rd Edition)

Pure fun. This is a great book. It's the best I've ever read (toghether with "Embedded Linux Primer").
The author not only knows what he says (and writes...), but he understands it deeply and he is able to explain it to you in an easy way, with fun.
You don't need to be a linux kernel developer to find this book useful: you can find it very interesting to read how skilled, clever and expert developers solved difficult problems (often in a surprisingly easy way...) at kernel level, and you can use this knowledge in your own user-level world (or in the embedded world, like I do).
The only part I've found a little bit boring is the Virtual Filesystem chapter. My fault, anyway!Get more detail about Linux Kernel Development (3rd Edition).
