These are great resources. Best advice I was ever given when starting CS and learning C was from the headmaster (hi RR!) asking me "What about Linus's linked-list? Have you looked at them?". Up to that point, this (new) headmaster was seen by the students as "that non-tech guy here to administrate the school" and he was opening my eyes on the biggest codebase residing on my own computer that I never bothered looking through: the Linux kernel code. As someone says further down the comments, this is not a specific Linux thing: looking at how Java HashMaps works or how Ruby implements "map" are great resources and you'll always get bonus points in an interview for referencing algorithms from "proven" source codes.
