In the end the Linux kernel is just a big project written in C.
Instead of asking what files do you need to understand. You should ask
yourself what subsystem do you want to learn?

Focus on functionality and browse the code to understand. As others
pointed before there are lots of good books that will give you a high
overview of the kernel.

The first book that I recommend reading is Linux kernel development by
Robert Love, but only if you have already read a book on operating
system concepts. The best book for me is Andrew Tanenbaum's Modern
Operating Systems.

Hope it helps,
