Very pleased to say that I've now finished the first draft of my book, The Linux Memory Manager.
https://linuxmemory.org/
This represents 2 years of evenings and weekends, tons of research, 99.9% from first principles and the kernel source.
There's still plenty of editing to go, but the content is written! 1,351 pages of it (!).
I am not sure on ultimate release date as it depends on how the edit goes, but we're closer now :)
As you can see from the pic, I'm very very tired but also very happy to have finished.
I think I'll chill for a while before I get back to a leisurely edit, read books, watch films, play games, spend time with my wife and cats and do a bunch of stuff the book took out of my life for a long while!
Now I'll go to bed early I think! :)

I found "Unusable Free Space Index", which is a good metric to represent the amount of fragmentation, from Mel Gorman's paper[1]. I implemented it as a script called 'ufsi.py'[2], and used it in researches and profiling. While using it, I started wrongly thinking the name of the metric is "ufsi". I have again used the wrong name in LSFMM session of yesterday, and apparently it made one people or two bit confused. Clarifying here, though I unsure how many people will read this. Sorry if I made you bit confused, again.

I just sent two sets of patches for DAMON-based tiered memory management [1] and access/contiguity-aware memory scaling[2]. These have been on the back burner for a while, but I was able to get a little more work done this time around because they are the main topics of tomorrow's LSFMM session - presentation-driven development definitely works!

Just uploaded the first draft[1] of the slides for LSFMM+BPF 2024 DAMON talk[2]. Note that it is just a draft, and therefore will be (significantly) changed until the talk, though!

@kernellogger FWIW, seems the glorious commit was 066ff875952b ("cves issued for some 6.8.8 commits").
```
vulns$ git ls-tree 066ff87 cve/published/*/*.json cve/rejected/*/*.json | wc -l
1002
vulns$ git ls-tree 066ff87~1 cve/published/*/*.json cve/rejected/*/*.json | wc -l
959
```
And in a way of sorting the CVEs, the 1000th CVE is CVE-2024-27019 (https://lore.kernel.org/2024050150-CVE-2024-27019-e3d4@gregkh).

The #Linux #kernel's #CVE team just published their thousandth CVE[1]. 🥳 🙃
This happened 78 days after the effort was announced[2].
Note, 26 of the 1003 CVE entries published so far were later rejected. For details check https://git.kernel.org/pub/scm/linux/security/vulns.git/ or https://lore.kernel.org/linux-cve-announce/
