I wrote a book on Linux Memory Management, published by 
@nostarchNo Starch Press - it's a comprehensive 1300 page exploration of Linux 6.0's memory management code, depth-first, diving into the code and REALLY explaining how things work.
The idea is to avoid hand waving as much as possible and literally explore what the kernel _actually_ does.
It's full of diagrams and careful explanations of logic including a ton of stuff you just can't find anywhere else.
It's currently available in its entirety in draft form via early access when you pre-order.
It's available at https://nostarch.com/linux-memory-manager
