Wait, am I still on LKML? Due to all those emojis, it feels more like a WhatsApp chat. 😄

Whatever, for a reply to this great patch submission from @vbabka[1] it somehow fits – and made me slime. So thanks, @hyeyoo!

[1] to quote: ""It's a debugging feature [that is removed by this patch]. However, thanks to the advent of LLM-based reviews, we are not adding bugs to the anymore, so it's unnecessary now.""

Finally, with Clang 22's release, here's v1 of Linux kernel slab cache partitioning with help of Clang's AllocToken feature: https://lore.kernel.org/all/20260331111240.153913-1-elver@google.com/

"Separating pointer-containing objects from pointerless objects and data allocations can help mitigate certain classes of memory corruption exploits: attackers who gains a buffer overflow on a primitive buffer cannot use it to directly corrupt pointers or other critical metadata in an object residing in a different, isolated heap region."

@vbabka @corbet Our headquarters is already designed for the cat boss :) The desk looks nice though!

@ffmancera @ljs FWIW, I use 'hkml patch format' [1] for all my patches.

Being able to read kernel patch AI review comments that provided by sashiko.dev [1] on terminal was nice. Showing the entire review status and sharing the outputs together with my review of the review were bit tedious for me. Particularly for the sharing of my review of the review, I wanted to just continue the mail based workflow.

So I implemented new hkml features for forwarding sashiko review status and comments. It feels much comfy. The documentation [2] is also updated.

Of course, once sashiko.dev provides the email service, it will be much more easier to use. Then, the hkml features could be deprecated and make my life easier. But, meanwhile, the new hkml features will help me.

And sashiko.dev, the kernel patch AI review service, is now officially announced! https://lore.kernel.org/all/7ia4o6kmpj5s.fsf@castle.c.googlers.com/

Yesterday I learned [1] existence of sashiko.dev, which provides AI reviews for kernel patches, thanks to @monsieuricon 's awesome b4 reivew feature.

Today I added new hkml features [2] for showing the AI review on hkml. It can be used interactively (hkml list -> open menu -> 'handle as patches' -> 'show sashiko.dev review') or from command line (hkml patch sashiko_dev <msgid>).

It was possible only owing to the awesome b4 source code. Huge appreciation to @monsieuricon for b4 development! Of course, great thanks to sashiko.dev developers!

@monsieuricon Today I learned the existence of sashiko.dev. I don't know who made it for what purpose, but it allowed me finding a bug in a DAMON patch. I'm already a fan of it.

I just posted [1] my third LSF/MM/BPF 2026 [2] topic proposal. Hopefully this is my last topic proposal for the conference.

Subject of the proposal is: "DAMON Updates: Tiering, Pagel Level Monitoring and DAMON-X"

@mpdesouza @monsieuricon I guess you want to send all replies at once? Indeed 'hkml' has no good feature for such things. I do such kind of batched replying with below workaround.

After writing a reply, 'hkml' asks you if you really want to send it, or not. If you say no, 'hkml' will ask you if you want to save and tag it as 'drafts'. In the case, if you try to reply to the mail again, 'hkml' finds the draft reply and ask you if you want to continue writing the draft. You can also list all drafts using 'hkml list drafts' and continue writing it, using the menu.

So when I want to review all patches and then send all comments at once, I save my drafts for each patch, and iterate multiple times on each draft for adding more comments on the drafts. Once I think all replies are ready to go, I send those one by one, but with no more draft updates.

Maybe I can add a new hkml feature for sending all drafts for a given thread at once.

DAMON release news for v6.19-rc1..v7.0-rc1 is just posted [1]. To quote the "tl;dr:"

'''
Interesting DAMON development ideas including PMU-based extension, automated
THP application, and new DAMOS quota auto-tune metrics for CXL-based tiered
memory systems have been proposed.

Two DAMON topics for LSF/MM/BPF are proposed.

In the time period, 12 grateful contributors landed 75 commits on the linux
mainline.
