🔥So many Linux CVEs! To make them scarier, I asked my favorite LLM to come up with names. As you know, only vulnerabilities with a decent name and a URL are serious. ;-)

We are on the track [1]. Transitioning DAMON from" data access (and attributes) monitor" to "data attributes monitor" is the major changes for the ongoing DAMON extension project. The project is for per-CPUs/threads/reads/writes monitoring with AMD IBS-like h/w features. The patch series for that has been merged into mm-new today.

Linux 7.2-rc1 is released. Hence I posted DAMON newsletter [1] for the 7.2-rc1 cycle.

TLDR: The last development cycle for DAMON was the busiest cycle of its mainline history (~5 years, since 2021 September). 12 Authors landed 106 DAMON patches for a number of changes including 7 new features on the mainline. A roadmap for extending DAMON to utilize AMD IBS, Intel PEBS like h/w features and do per-CPUs/threads/reads/writes monitoring is made.

DAMON project blog got [1] its first and grateful post contribution for TLB flush policy, which made many people confused. You can now read the contributed post [2] from the blog. This will help more people better use DAMON and get real wins.

Multiple people including myself started their own projects for extending DAMON to support multiple access check primitives. To reduce unnecessarily duplicated efforts, I just shared a roadmap [1]. I hope this to help making all stakeholders winners, or at least reduce confusions.

So it seems I got talked into doing a "live maintainer session" with the Linux Foundation on June 2:

I will doubtless have all kinds of witty things to say ... mark your calendars ...

@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 :)
