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 :)

@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.
