Looking for resources that can help getting ‘into’ the Linux code. Could not get much help on Google. I have no issues on the distro covered by the book/resource, but will like if Fedora is the base. Also, it would be great if the resource is well maintained and updated.

Note that you will need to be familiar with Operating Systems concepts to even understand the concepts of how memory is allocated, how processes are scheduled, and whatnot. Also, the code of the linux kernel is monstrously complex.
You are undertaking a daunting task. But have fun with it. You might want to start with a small device driver’s code.
