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.

If the kernel source code is present in your system, you can find it under the /usr/src/linux-<Version> directory, where <Version> must be replaced with the source code kernel version you are dealing with. You also can find the last kernel source code at https://github.com/torvalds/linux.
After installation, the kernel sources are located in /usr/src/linux-<kernel-version>. If you plan to experiment with different kernels, unpack them in different subdirectories and create a symbolic link to the current kernel source.
The kernel source tree consists of all the source code for the kernel and device drivers for all supported processor architectures. The original kernel was developed to support 32-bit IA-32-based systems (starting with the 80386).
So kernel is also software (more specifically system software) and it is programmed in one of the many available programming languages. So kernel source code means that code.
this looks promising:

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.
