Outreachy is getting squeezed financially from reduced funding related to diversity programs and reduced funding for open source orgs. Can you help us spread the word about how important the program is and help us connect to folks who might contribute funding?

Just realized the new member looks similar to the penguin of FB kernel team logo hat I found from https://opensource.fb.com/linux/ (file name: kernel-team-logo.svg)

The bubble is not popped yet. The 30-days PyPI downloads of 'damo' has doubled (8,000 -> 16,000) again, about ten days after the last doubling.

DAMON project site's main page (https://damonitor.github.io) was redirecting[1] to a personal blog post, with its hidden real main page[2]. Now DAMON has its own project blog, and does not redirect[3] to personal blog anymore.

I posted[1] an RFC patchset for DAMON debugfs interface removal a few days ago. Unless someone objects, the change will be merged soon, maybe into v6.14-rc1.

After about ten days from the last posting[1] of damo [2] monthly downloads record, the count has doubled (4,000 -> 9,000) again. The time for doubling the count has been reduced from 18 months to 7 months, then to 10 days this time.

Because daily stat graphs on PyPI are not very convenient for monthly download stats, I plotted the 'rolling 30-day downloads' count. It shows this might be a temporal bubble that will pop soon. But, doubling is doubling. I'll seize tonight :D

At OSSummit Europe last month, I and Honggyu Kim presented[1] a few DAMON recipes including those for memory auto-scaling and CXL memory tiering. The video is now available at YouTube[2].

The next instalment of Linus vs. Kent – and Linus seems to be on the edge:

"[…] I'm contemplating just removing entirely from the [ ] mainline tree. Because you show again and again that you have no interest in trying to make mainline work. […]"

For the full discussion, start here: https://lore.kernel.org/all/cphtxla2se4gavql3re5xju7mqxld4rp6q4wbqephb6by5ibfa@5myddcaxerpb/t/#m631c24cd07f5820a4cbff8f25dff1d1a0c3cf2e7 (the quote is from one of the later mails from Linus).

Wonder how many more "strikes" are needed? I think we've seen far too many already. Heck, even the Phoronix commenters seem to think enough is enough.

Monthly downloads of DAMON user-space tool (DAMO)[1] from PyPI took about 18 months to surpass 2,000. About only 7 months after that, it exceeded 4,000 today!

, which allows scheduling policies to be implemented as programs, has been merged for 6.12:

https://git.kernel.org/torvalds/c/88264981f2082248e892a706b2c5004650faac54

See https://lwn.net/Articles/922405/ for a description of what it does and https://lwn.net/Articles/972710/ for the controversy it caused that is the reason why it took so long to land in mainline.

Sched_ext Merged For Linux 6.12 - Scheduling Policies As BPF Programs

Linux 6.12 is shaping up to be a heck of a kernel update! Following real-time "PREEMPT_RT" going mainline after twenty years and many other kernel features merged this week, Linus Torvalds just pulled in the much anticipated sched_ext code!..

My Kernel Memory Management LPC Micro Conference talk titled "DAMON: Long-term Plans for Kernel That {Just Works,Extensible}" was successful.
The video[1] and slides[2] are available. I was obviously nervous since I forgot contents of the slides due to the great talks from two previous speakers (I highly recommend you to watch those). I like it though, since it reminds me how humble I am ;)

MM pull request for Linux v6.12-rc1 is posted[1] by Andrew Morton. Important fixes / cleanups for DAMON are included:

- mm/damon/lru_sort: adjust local variable to dynamic allocation
- misc fixups for DAMON {self,kunit} tests
- replace per-quota region priorities histogram buffer with per-context one
- Docs/damon: update GitHub repo URLs and maintainer-profile

I believe it is a good list of changes for next LTS kernel candidate.

Lots of people thanked me for my work on b4 this week. It feels very nice, but I want to remind everyone that b4 wouldn't be possible without public-inbox. Please email Eric Wong (privately) and thank him for his work -- I am pretty sure he can use some good vibes.
