#3Since you do not mention if you're already a pro with OS internals and implementations, I will assume, maybe incorrectly, that you're not.
So in that spirit, try the XinuOS. It has the complete source code for a minimal, clean and practical OS. Search for the book explaining it inside out.
xv6, a re-implementation of Dennis Ritchie's and Ken Thompson's Unix Version 6 (v6) also comes to mind.
And C. Don't forget to sharpen your C skills.

#4Understanding the Linux Kernel, Third Edition is now horribly out of date, but it's a good place to start if you've never read it before.

#5Something I've done a couple times is trace the execution of a system call by reading the code. LXR is really helpful.

#6Read the Linux programming interface by Michael Kerrisk. It will tell you what Linux should be doing for you ( the api basically and what subsystems exist). Read lwn, kernel newbies to get a feel of what’s happening in the kernel.
Get knowledge of operating systems ( I like the minix book by tanenbaum ). Learn about Linux internals ( I like linux kernel development by Robert love)
Then, pick bits you’re interested in and jump !

And to track that down, use https://elixir.bootlin.com/linux/latest/source to ealisy browse between kernel version, functions, etc..

#8Linux Kernel Development by Robert Love. It's spectacularly out of date but is still a good starting point. And Elixir is very helpful for browsing the source code and comparing chnages across kernel version: https://elixir.bootlin.com/linux/latest/source

#9Without more details I assume you just want the source code and documentation. One could either clone the repositories [1] or just browse the CDN access to the docs and kernels. [2] The latest kernel is in the v6.x directory.
