@lwn @jzb Seems the button is shown only when the filtering feature is enabled. I didn't enable filtering before. After enabling filtering using the "Enable filtering" button on https://lwn.net/MyAccount/ I can show the "Mute user" button on comments. Thank you for letting me know this!

@lwn @mxk @neverpanic @jzb I cannot find "Mute User" button. But I can find the feature from https://lwn.net/MyAccount/commfilters/
From the web UI, I can go to the page by clicking my account name, and then "Edit filtering" button.

@nyc @lwn Interesting. I wrote and used a program [1] for making such research-purpose artificial memory fragmentation. I also wrote a script [2] for measuring how much the memory is fragmented. If you find something that DAMON might further help, please let me know, I will be happy to help :)

@lwn Selective DAMOS quota auto-tuning logic [1] is picked as one of interesting changes for Linux 7.1, by LWN. It is a great pleasure to see what I developed with the community is mentioned in such a named place.

@monsieuricon @ljs How about taking the four letters and add only "x" at the end? It may sound luxury to some people.

I just posted [1] DAMON news letter for Linux 7.1-rc1 release cycle. We shipped two new features and two important internal improvements. Contributors are continuously making progress. Sashiko made us quite busy.

I just posted [1] an RFC patch series. This will enable light-weight cgroup or any page level information-aware access monitoring.

While implementing it I realized this can be a very important part of DAMON's future. I personally call it "DAMON reboot" project.

It was hugely motivated by LSF/MM/BPF [2]. Conference-driven development works. Huge thanks to the committees.

LSF/MM/BPF preliminary schedule [1] is shared [2]. Seems there will be two DAMON topic sessions. Time to really focus on the preparation.

@vbabka @oleksandr @liskin Maybe mm-new is a better suggestion if they need more stability.

@ljs I'm so sorry to hear what happened to you and your colleagues. Nonetheless, as you may already know, sometimes something happens, and there are many maintainers who are working under such unfortunate condition. When it happend to me, knowing that I'm not the only one was helpful, so I just wanted to say this to you, too. Also as you may already know, sometimes good things also happen, so I wish those happen to you soon. Also let me know if there is anything that I can help other than reviewing more mm patches.

Thank you @irogers ! Could you please further share how I can opt in, or check if I'm already opted in? I was thinking DAMON is already opted in [1] but I might missing something.

@irogers Seems sashiko-bot is a bot that recently started working. Do you know more details about the bot including how I can use that? If so, could you please share those?

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

https://lore.kernel.org/all/ac0HSfV05ppXQKya@hyeyoo/t/#u

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."
