Maybe it could help to firstly focus on data structures/types rather than functions;
and I would discourage to read code like a book, I mean from left to right and
from top to bottom. And, take a subsystem/part (even if it's very small) of interest
and just focus on it. For instance, I guess there is plenty of documentation on how
linux boots up: read it, and search through the source where what you have read is done.

compile your own kernel, if you haven't done it yet!
