I use TLPI as an optional text for my CS Operating Systems course! It's honestly the best resource for a comprehensive look at the innards of Linux. I actually even snip select pages for lectures.
People should do a foundation course to figure out which deprecated parts of the kernel source to avoid. It is nontrivial, but talking with the active developers will save a lot of guess work. =3
What a horrible selection for a university textbook! It doesn't get trivially updated every year to prevent reuse and reselling, so how is this supposed to generate more profit for the booksellers? /s
Seriously though, this book is fantastic, and far better than typical course textbooks. I'm honestly a little surprised that universities would select it.
Introductory LFD103 is a free course:
