Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I am trying to modify the redblack tree datastructure used in 2.6.24 and above kernels to some radix tree, for my university project. I dont have a proper guidance, and therefore stuck and dont know where to start. I dont know how to solve the dependencies if I change the datastructure. Anyone with suggestions??? please??
But this is the 'better' of the two - the other should be closed and merged into this.

Con Kolivas, IIRQ. Good for a search, anyway...
How can I evaluate the new kernel performance with reference to the actual 2.6.32 kernel? any tools?
The OP is asking about tools to evaluate kernel performance. While I honestly have doubts whether that is what is required (or, maybe, all that is required) I'll have a go at it, anyway.
Define what constitutes performance. (memory usage, execution time, latency, power consumption, 'smooth' multitasking (however you measure that), task switching efficiency and processor utilisation in a queued task environment...)
Is it the case that certain applications are more important to you than others? The consideration on the desktop are probably quite different from the consideration running a LAMP stack, so you'd want to know if you have a restricted area of application.
Have a look at Phoronix. They have a test suite and look at what they do. I'm not suggesting that you copy them, but you can understand what they do and learn from them, and a subset of their test suite might be quite useful to you. Or not, potentially, depending on the answers to the previous questions.
