@ljs @amonakov @pkhuong @thesamesam OK but let's go back to the more verbose way.
#define __alloc_pages_node(...) alloc_hooks(__alloc_pages_node(__VA_ARGS__))
#define __alloc_pages_node_noprof (__alloc_pages_node)Would that work then? Yes it's more (up to twice) #defines than we have now, but it wouldn't require us to rename the underlying functions to _noprof (and having see those _noprof symbols in perf, backtraces etc.).

@ljs @vbabka Thanks to both. Yes, I remember to read about new/concurrent/RCU friendly VMA tree at #lwn some time ago, I try fit more letters in the triangle, on the other hand R-B tree is something which students know… but showing maple can be motivation to search for more modern data structures in their future projects, I mention user-space RCU, cuckoo hashing from Knot DNS as well as others.
struct radix_tree_root page_tree; /* radix tree of all pages */Good catch, it seems to have gone in 4.17 kernel, when it has been renamed to
struct radix_tree_root i_pages;and it has been changed to
struct xarrayin 4.20. So this is evolution.So it should be updated to be modern.
VPFN (virtual page frame number) and physical (P)PFN is used by me to distinguish what is view and meaning of address bits before and after MMU translation. It highlights that translation cares only about page sized frames no full addresses. It seems that it is not only mine local invention - used even on WikiBooks/The_Linux_Kernel/Memory.
The goal is to provide mainly an overall picture not details to start hacking and contributions to the kernel so if it is “roughly” appropriate is important. But if some students are attracted to contribute to Linux it would be great outcome. We have more students contributing to #NuttX which is lower bar for starting. But some have contributed drivers to Linux as well.

@ljs Congratulation to the book publication. I hope to find some time one day and look at it myself or at least, will be able to make it available to my students with help of the #cvut library.
I have plea for you and @vbabka , I prepare for the next round of the Advanced Computer Architectures course. It is focused mainly to basic knowledge about progress from pipelined execution (basic course) to the super-scalar one in nineties to understand even later designs including GPUs, NUMA, etc. But I include even some amateur glimpse how is memory used in real system which is based on my already dated wander through Linux kernel sources. I would be very happy if you find time to look at the diagram on the slide 114 of the Lecture 6 and provide me feedback if there is something which is not true or have been changed considerably so I should correct it to not mislead my students. There are some more slides around where your expert feedback can save students from misleading information as well.

@mike805 @ljs The right wing, or rather the fascist value of intelligence, is doublespeak. It favours those who can build and develop any tech that gives them a competitive edge to censor, purge, destroy and subjugate all opposition.
