Please talk to us if you think you might be interested, and pass on a pointer to anybody else who might be a good fit.

Kernel Summit time table is uploaded!
The time for DAMON talk also updated together: https://lpc.events/event/17/contributions/1624/

Glad to see an SOSP paper is referencing and exploring DAMON: https://multics69.github.io/pages/pubs/memtis-lee-sosp23.pdf

@rostedt @vbabka I also occasionally encounter such situations. But instead of admitting the fact that I should finish that, I just lazily commit it, revert it and its dependents, and do the new work. The dirty history eventually reminds me I should finish that, or just forgive and drop those from the history.

Just submitted a BoF session for the second in-person DAMON community meetup to LPC. Hope it to be accepted and the community be gathered again like we did last year[1]!

My DAMON talk proposal for Kernel Summit track of Linux Plumbers Conference 2023 has accepted. We did DAMON talk every year at Kernel Summit since 2019, so this is the fifth Kernel Summit DAMON talk. Happy to have yet another chance. I hope it to be a place to discuss about future DAMON development works with core kernel developers.

@hyeyoo I miss the past that logcat live wallpaper[1] was showing whole system log

@hyeyoo Thank you, you too!

@gregkh @KernelRecipes I was able to get the video by rewinding the livestream: https://www.youtube.com/live/xDHTn0auo2w?si=NXDpMbtEwDJyLZLD&t=14940

@mxk I indeed had grateful chances to earn very cool socks, but I wear only ankle socks 😎

@ljs I understand the feeling. Maybe I should make some sponsor t-shirts for LSF/MM that have DAMON logo together ;) Hmm, for that, should I make a foundation for DAMON? Wait, then would I need to design the logo first? 🖌

Grateful swags that I got from #osseu

@corbet @sjvn Send the emails my way, no one seems to ever actually want to talk to _me_ about these support dates for some odd reason...

So OSS Europe was an interesting experience, this year, in a way.

I did my usual talk, and started with the usual section on kernel releases. When talking about stable updates I tossed in a quick mention that six-year support from the stable team was being phased out — something I understood to be generally known for about the last year. Way at the end of the talk, as my last topic, I discussed at some length the stresses being felt by kernel maintainers.

@sjvn wrote an article about the talk (https://www.zdnet.com/article/long-term-support-for-linux-kernel-to-be-cut-as-maintainence-remains-under-strain/) and made a connection between the stable-policy change and the maintainer issue — something I had not done in the talk. It was a bit of a shift from what I said, but not a bad article overall.

Then the rest of the net filled up with other writers putting up articles that were clearly just cribbed from SJVN's piece — sometimes with credit, sometimes without. I'm getting emails about what a terrible idea this all is, as if I had anything to do with that decision or can somehow change it. I have, it seems, taken away everybody's six-year support, and they're not happy about it.

All because of a 30-second mention of a change that was made public something like a year ago. My 1.5 minutes of fame has given me a new appreciation for this old quote from Rusty Russell: "when a respected information source covers something where you have on-the-ground experience, the result is often to make you wonder how much fecal matter you've swallowed in areas outside your own expertise."

My OSSummit EU DAMO talk[1] video is available at https://www.youtube.com/live/ggx9ZssPHU8?si=fP3dinUeJ8pB4KMr&t=16329

The slides are also uploaded to the talk intro page[1] and GitHub[2].

@ljs Agreed. I hope fully self driving (a.k.a self-tuning) DAMON be available before that :)

@ljs I'd rather walk until real fully self driving cars be available ;)
