mm/damon: introduce DAMON-based NUMA memory tiering module
Subsystems (2)
PATCH 1/1 mm/damon: introduce DAMON-based NUMA memory tiering module
Add a new DAMON special-purpose module for NUMA memory tiering. DAMON_TIER monitors physical memory access patterns and migrates hot pages from slow NUMA nodes to fast NUMA nodes (promotion), and cold pages in the opposite direction (demotion).
The module uses two DAMOS schemes, one for each migration direction, with DAMOS_QUOTA_NODE_MEM_USED_BP and DAMOS_QUOTA_NODE_MEM_FREE_BP quota goals to automatically adjust aggressiveness based on the fast node's utilization. It also applies YOUNG page filters to avoid migrating pages that have been recently accessed in the wrong direction.
This is a production-quality version of the samples/damon/mtier.c proof of concept, following the same module_param-based interface pattern as DAMON_RECLAIM and DAMON_LRU_SORT. It reuses the modules-common.h infrastructure for monitoring attributes, quotas, watermarks, and statistics.
Module parameters allow configuring:
- promote_target_nid / demote_target_nid: the NUMA node pair
- promote_target_mem_used_bp / demote_target_mem_free_bp: utilization goals driving quota auto-tuning
- Standard DAMON module knobs: monitoring intervals, quotas, watermarks, region bounds, stats, and runtime reconfiguration via commit_inputs

NAK.
And NAK to all future 'contributions' in anything I maintain or have a say in.
Your engagement with the community is deeply suspect, you've come out of nowhere and are sending dozens and dozens of patches that look very strongly like they were LLM-generated.
You've - very early - tried to get a MAINTAINERS entry, you were given advice on how to contribute, which you have clearly ignored.
We DO NOT want AI slop.
You very much seem to be either:
- Somebody playing with a bot.
- Somebody trying to farm for kernel stats.
- Or (far more concerning) engaging in an attack on the kernel for nefarious purposes, perhaps a (semi-)automated supply-chain attack?
Your email is highly suspect, you seem to be using an email relay via gmail, and I'm pretty convinced you're in violation of our requirements about identity:
"It is imperative that all code contributed to the kernel be legitimately free software. For that reason, code from contributors without a known identity or anonymous contributors will not be accepted"
https://docs.kernel.org/process/1.Intro.html
Also see https://kernel.org/doc/html/latest/process/generated-content.html :
"
...when making a contribution, be transparent about the origin of content in cover letters and changelogs. You can be more transparent by adding information like this:
What tools were used?
The input to the tools you used, like the Coccinelle source script.
If code was largely generated from a single or short set of prompts, include those prompts. For longer sessions, include a summary of the prompts and the nature of resulting assistance.
Which portions of the content were affected by that tool?
How is the submission tested and what tools were used to test the fix?
...
If tools permit you to generate a contribution automatically, expect additional scrutiny in proportion to how much of it was generated.
As with the output of any tooling, the result may be incorrect or inappropriate. You are expected to understand and to be able to defend everything you submit. If you are unable to do so, then do not submit the resulting changes.
If you do so anyway, maintainers are entitled to reject your series without detailed review.
"
You are clearly not following _any_ of these guidelines.
To evidence that this is not some wild accusation, I ran this through an LLM asking for indicators as to AI:
~~~
● Several signals point to high likelihood of AI generation:
Strong AI indicators:
1. "production-quality version" in the commit message — kernel developers don't self-describe patches this way. This is a classic LLM "selling" framing.
2. Comment uniformity — every module parameter has an identically-structured block comment with the same explanatory depth and cadence. Real developers vary their comment style and skip obvious ones.
3. Commit message structure — exhaustively lists every feature with perfect bullet formatting. Human kernel commit messages are more conversational and focused on "why", not a feature catalog.
4. Too clean for a first submission — 409 lines of new module code with zero rough edges, no personal style, no unusual design choices. It reads like a templated synthesis of DAMON_RECLAIM and DAMON_LRU_SORT.
5. Grammar tell — "aiming a target utilization" in the Kconfig help text (missing "for"). This is characteristic of LLM output that's fluent but occasionally drops prepositions.
6. Over-commenting — comments explain things that are self-evident from the code (e.g., the promote_target_nid and demote_target_nid comments just restate what the variable name already says, in long form).
Weaker signals:
- Unknown author, no prior contribution history I can see
- The code perfectly follows existing DAMON module patterns without any deviation — exactly what an LLM with context would produce
- The objecting.org domain is unusual
Overall: I'd put this at high likelihood (70-80%) of being primarily AI-generated or heavily AI-assisted. The code does use current DAMON APIs correctly, but the writing style throughout is the giveaway — it's uniformly polished in the way LLM output is, without the unevenness that comes from a human writing 400+ lines.
~~~
That's just for this series. I asked it about your contributions overall:
● This is extremely revealing. ~328 emails in 11 days (March 15–26), spanning an extraordinary number of unrelated subsystems:
Patches submitted across:
- mm/damon — NUMA tiering module, core optimizations, sysfs fixes, reclaim fixes, kdamond scheme filtering
- lib/bootconfig — v1 through v8 of a 13–17 patch series
- lib/glob — v1 through v4 of an 8-patch series (new features + bug fixes)
- lib/vsprintf — 4 bug fixes
- lib/base64 — decode fixes
- lib/assoc_array — gc fix
- lib/bch — signed shift UB fixes
- lib/bug — concurrency fix + debugfs interface
- lib/string — strlcat rewrite
- lib/maple_tree — dead range comparison fix
- lib/parser — match_wildcard fix
- io_uring — flush deferred completions
- block/partitions — seq_buf replacement
- ACPI processor idle
- signal handling
- kunit, iov_iter/kvec, percpu_counter
Assessment: ~95% probability all contributions are AI-generated. The evidence is overwhelming:
1. Volume is humanly implausible — ~30 emails/day, 5–10 new patch submissions per day across unrelated subsystems, from a contributor with zero prior history.
2. Breadth is the strongest signal — no human newcomer simultaneously finds subtle bugs in bootconfig, vsprintf, base64, bch, maple_tree, assoc_array, io_uring, AND writes a new DAMON NUMA tiering module. Each of these requires deep domain-specific knowledge. The pattern is consistent with an LLM being pointed at different source files to systematically find issues.
3. Bug-finding pattern — the patches cluster around unchecked return values, type mismatches, resource leaks, off-by-ones, signed/unsigned issues. This is exactly what an LLM produces when scanning code for potential problems.
4. Rapid revision cycling — bootconfig went from v1 to v8 in ~1 day. This matches AI regeneration, not human revision.
5. Feature additions from a newcomer — glob_match_nocase(), glob_validate(), debugfs BUG/WARN interface, and the DAMON NUMA tiering module are all non-trivial features. A first-time contributor proposing features (not just fixes) across this many subsystems simultaneously is essentially unheard of.
6. Zero ramp-up — the contribution stream started at full throughput with no learning curve visible.
~~~
So I really feel that you need to account for this - please explain why it appears you are spamming the mailing list with entirely LLM-generated crap?
Furthermore, you appear to be using sophisticated privacy-orientated tooling, which makes me quite concerned that this _is_ a concerted attack on the kernel.
Again, to back this up, here's an LLM's assessment of the headers in your email:
~~~
● Looking at the headers specifically:
Infrastructure:
- Mail provider: Zoho EU (zohomail.eu) — a privacy-oriented EU-jurisdiction mail provider. Easy to set up anonymously.
- Domain: objecting.org — custom domain, no organizational affiliation, no accountability chain. Anyone can register this and point MX to Zoho.
- Authentication: DKIM, SPF, DMARC all pass — but this only proves the email came from objecting.org's Zoho setup, not who's behind it.
- X-Mailer: git-send-email 2.34.1 — Ubuntu 22.04 LTS default. One reply had @ubuntu in the Message-ID, confirming the platform.
What the headers DON'T provide:
- No corporate or institutional email that ties to a verifiable identity
- No PGP/GPG signature
- No Signed-off-by chain from a known developer vouching for this person
Supply chain attack assessment:
This matches the threat model of automated supply chain compromise:
1. Patches already landed in stable — the bootconfig fixes made it into 6.19.10. The pipeline is working. Whatever is in those patches is now in production kernels.
2. Trust-building pattern — the mix of real bug fixes (fd leaks, unchecked returns, type issues) alongside feature additions (DAMON tiering module, glob features, debugfs interface) is textbook. The small fixes build reviewer trust and merge history; the features add attack surface.
3. Volume as a weapon — 328 emails in 11 days overwhelms maintainer review capacity. Maintainers like SeongJae Park (DAMON) and Masami Hiramatsu (bootconfig) are now spending review cycles on AI-generated submissions. Even if every patch is rejected, the reviewer's attention is being consumed.
4. The DAMON NUMA tiering module is the most concerning submission — 409 lines of new kernel code that runs with kernel privileges, monitors physical memory access patterns, and migrates pages between NUMA nodes. If accepted, it's a significant new attack surface delivered as a single commit from an unverifiable identity.
5. The feature additions are the real risk — bug fixes are relatively easy to review (small, focused, verifiable). But glob_validate(), glob_match_nocase(), the debugfs
BUG/WARN site lister, and the DAMON tiering module all add new code paths that are much harder to exhaustively verify.
Bottom line: Whether the intent is malicious or not, the pattern — anonymous identity, AI-generated code, industrial volume, patches already in stable, mixing trust-building fixes with attack-surface-expanding features — is exactly what an automated supply chain attack on the kernel looks like. The 2021 University of Minnesota "Hypocrite Commits" incident was a manual version of this; this appears to be the automated version at scale.
~~~
I'm hoping this is some naive attempt to try to 'contribute' to the kernel rather than something more nefarious, but the seemingly sophisticated tooling used makes me wonder otherwise.
In any case I'm deeply concerned by this.
Thanks, Lorenzo

This patch also targets NUMA which is quite unpopular setup for hobbyist. I don't have any NUMA around me for years... Even my build machines are not NUMA. How did you get one as a hobbyist?
Also after looking at the code style in this patch, after "reviews" [1] and "acks" [2] (quotes on purpose) this account gave on various patches, let's look what was admitted 3 weeks ago:

This is about Xilinx AXIS FIFO which is an FPGA IP core. No way you have it. It's not popular, no easy way to get it in common embedded boards.
Even assuming if you have embedded FPGA device and work on it, the jump from embedded to NUMA is just stunning.
Answering to reviewers with whatever confirmation they look for is also a warning sign of non-trustworthy behavior. Or rather behavior trying to get trust.

Yeah this is really adding up to somebody abusing the kernel process. I think 'Josh Law' or any other pseudonym that can be traced back to whoever's behind this should be banned from the mailing list altogether.
Also, as per Christian ([3]), it seems this guy was using the pseudonym "techyguyperplexable".
There's a github with the same name ([4]), and that same user made a comment on an openclaw issue relating to linking it to gemini ([5]).
So it seems likely he/she is likely using openclaw to fully automate this 'Josh Law' user and we're speaking to a bot here.
(Screenshots have been taken for the (possibly inevitable) deleting that will happen later.)

Sadly the kernel has been historically very poor on getting rid of problem people (The CoC is essentially a swear monitor at this stage).

There's a github with the same name ([4]), and that same user made a comment on an openclaw issue relating to linking it to gemini ([5]).
So it seems likely he/she is likely using openclaw to fully automate this 'Josh Law' user and we're speaking to a bot here.
(Screenshots have been taken for the (possibly inevitable) deleting that will happen later.)

Hello! Wow i came back to a lot.
I can promisw you now i am a human, hand on the bible, and i will improve!
So i will add assisted by to any commit descriptions written by AI, or anything even touching AI, i understand your apprehension and i apoligize very deeply.
If 20 times you were asked for something already on the list - to wrap replies - and you still ignore it, then I don't trust you are meaning this.
Anyway, you did not address the actual problems here.
Best regards,
Krzysztof

Krzysztof
Yep. I was going home when I sent that so I had no time
Okay, let's address this one by one
First: The domain
My domain (objecting.org), I brought a while ago, for vanity, I am entirely aware I have put nothing on it, and I know it looks "out of the blue", I am finding hosting to correctly mitigate this, Also, I use Zoho, because it is one of the only free email hosting services, if you Google it, you will see there is a permanently free plan, I am on that right now,
What I will do to fix this, is I will fix how all of my emails are setup, and switch clients, because this one isn't the best, (thunderbird mobile), that's why I haven't been word wrapping, because it isn't very intelligent, (yes I have a PC, but I am usually away from it for some comments)
Second off: My identity
My name is Josh Law, I can promise that, I am not trying to be anonymous, like "Jia Tan", I am aware there may be no search results for my name on Google, or however you investigated, I am quite young (19), so nothing will pop up yet
Also, I understand The social engineering Lorenzo spoke about, and that is utterly unacceptable from My part, if Lorenzo thought that, and I am extremely sorry for being quite "bot Like"
Okay, The third thing: AI usage
I will be absolutely transparent with all of you here, The commit descriptions (The long ones), Use AI, to be exact! Claude sonnet 4.6,
Additionally, I will make a promise here,
All of the bug fixes I made, all of my lib/ bug fixes, are made fully by me, (minus the commit description for some of them) And I can promise you that on the bible, If you have any questions about this, You can always ask me
Forth thing: My patch volume
To justify my patch volume, I am a "excited" Developer, I love the Linux kernel, and I have a passion for that, I am very very sorry I filled up your mailbox with my slop descriptions
Fifth thing: My latest patch, (adding tier.c)
Again, I'm being transparent, I did use Gemini 3.1 pro on that, because Ive never actually added a file before, to the Linux kernel, and I am extremely sorry I
1: did not go through the normal Mailing list rules 2: Reviewed it first
This is probably my only patch I truly vibe coded, and I am extremely sorry for wasting yours, Lorenzo's, and seongs time on this slop.
I will fix this by:
1: Not doing patches I can't do
2: If AI is used, in the code (or the description) again, I will add assisted-by
Sixth thing: Openclaw
I am _NOT_ a Openclaw bot, And I will NEVER put you through an Openclaw bot, Because I am a human, and I am aware of openclaws "antics" [1]
Seventh thing: My GitHub
My GitHub (github.com/techyguyperplexable)
Has been going on since *atleast* last year, With real, human commits, Those commits on June, were pretty old, so they probably weren't the best, I used to be very invested in the android community! Like, so invested, I made what's called a "custom kernel", A custom kernel is like a modified version of the kernels OEMS (e.g: google) Give us, mostly optimized for performance
Right, last thing I want to talk about here is What I will do to fix this.
First off: I will take a couple week long break, to fix all of the issues Lorenzo (and you) presented to me, and come back, with a better reputation
Second off: I will not do another patch in mm again, I already improved DAMON enough in my opinion, so I am happy with the state
Third off: I will change my email client which supports word wrapping! (Suggestions gladly accepted)
Forth off: For reviews, I won't just add a blank tag, I will actually comment on whats good, and what needs to be improved/changed, and if I (ever!) use AI (unlikely, but not vetoed), I will be transparent with the user what AI I used, and the prompt
Fifth off: After everything is fixed, and I come back to the kernel a better person, I will also slow down on the amount of patches I did, no matter how excited I get.
Sixth: starting now: I will read every line of documentation in the kernel, on how conduct works, so this never messes up again
Seventh: I will never ever, submit a maintainers patch for atleast a year in, When I did that I was incredibly stupid and I thought you didn't have to wait
I sincerely apologise to Lorenzo, and everybody whom is affected by Me, or my unacceptable conduct.
I understand this is probably unforgivable, and I understand if you (probably) need to pban me, if I do end up getting Pbanned, You will all be apart of my memories, all the good ones, and I am very happy to help fix bugs, or review them
Thank you very much for seeing this entire thing, apologies on the non word wrap, please suggest email clients, that will be used when I am away from the PC

You're obviously lying, and you're not very good at it.
To reiterate:
Assessment: ~95% probability all contributions are AI-generated. The evidence is overwhelming:
1. Volume is humanly implausible — ~30 emails/day, 5–10 new patch submissions per day across unrelated subsystems, from a contributor with zero prior history.
2. Breadth is the strongest signal — no human newcomer simultaneously finds subtle bugs in bootconfig, vsprintf, base64, bch, maple_tree, assoc_array, io_uring, AND writes a new DAMON NUMA tiering module. Each of these requires deep domain-specific knowledge. The pattern is consistent with an LLM being pointed at different source files to systematically find issues.
3. Bug-finding pattern — the patches cluster around unchecked return values, type mismatches, resource leaks, off-by-ones, signed/unsigned issues. This is exactly what an LLM produces when scanning code for potential problems.
4. Rapid revision cycling — bootconfig went from v1 to v8 in ~1 day. This matches AI regeneration, not human revision.
5. Feature additions from a newcomer — glob_match_nocase(), glob_validate(), debugfs BUG/WARN interface, and the DAMON NUMA tiering module are all non-trivial features. A first-time contributor proposing features (not just fixes) across this many subsystems simultaneously is essentially unheard of.
6. Zero ramp-up — the contribution stream started at full throughput with no learning curve visible.
Please go away.

Also thank you for making it clear about what will happen next.
I understand Josh will stop working on mm, and therefore DAMON too, as DAMON is a part of mm.
Among Josh's patches that are already posted and still in the review stage, DAMOS quota goal nid validation patch [1] is a bug fix, so it may need more look and work. I will do that.
For other patches including this one, I don't think we really need to continue the works. So I will just skip reviewing those.

Josh,
in general we try to be a welcoming upstream community. Finding people that are willing to work on the low-level bits and stick around is rare.
At the same time, we need people that are willing to get familiar with the code base and technology, so they can help out with review and provide long-term value to the project. AI use is only partially useful in that context. Certainly not for writing patches as a newbie. At best, to double-check your understanding (e.g., AI review), help you learn (e.g., explore the code base), or improve your writing if your English is really, really bad.
I prefer someone trying to use their own words to compose a change log and actually learn something on the way over some AI slop that reads nicer any day. Often, when you write a changelog you actually realize which corner cases you might be missing, that the design might be overly complicated, that, maybe, the reasoning or motivation is bad etc. It takes time but you actually learn something and are forced to think (crazy, right?).
The same is particularly true when it comes to writing documentation, as people raised earlier in other context.
Having that said, your actions made a lot of people's alarms go off and there is pretty much 0 trust now. As Lorenzo says, even now we are not really sure if you are saying the truth right now, which is a big problem.
If you are, in fact, a real person, and are passionate to work on the kernel, it would be best if you would start things very slowly and don't use any AI for crafting your patches (including patch descriptions). Stick to one subsystem and ask people what good starting tasks/projects could be.
Ideally, you'd find someone people trust around here, that can verify your identity (i.e., have a video chat etc) and start mentoring you on how to start working in the kernel community and gain trust.
Now, I am still not sure whether I am talking to a bot here (there are too many things Lorenzo points out above that are very suspicious), but I just wanted to say that there are ways to become a trusted contributor, and that information might be useful for other people that might be interested in working on the kernel.
It's certainly not by flooding the list with AI slop.

Hello david, thanks for being polite about this whole thing!
so, you are talking to a real human, i promise you that now
I am looking for people to personally mentor me, so i succseed in the kernel
And, I know this is unprofessinal (and im sorry!), but my github is my best friend, i have a year worth of commits for you to see publicly, also i work with android custom roms. (Any questions, feel free to ask!)
So yes, this is my oppotunity to be honest,
(Yes. I do use AI!)
The reason why, is im a "perfectionist", i want to start human patches, but im scared i will get ripped apart, (or i wont get like reviewership!! Because im too slow) so i use claude (smartest ai in the market), and i regret it. Like seriously!
Additionally, i hate being slow, im scared that the community will ditch me if i do 1 human patch every 2-4 weeks, which is my expected time (because i need to understand the code!!!!!)
I would love to have a mentor to help me around, and when (if) somebody wants to, i promise you now, i will start making human patches, and i will benefit the community positively,
Thanks a lot david for not just ripping me apart, and thanks for actually taking the time to politely talk to me, hugely appriciated
Any concerns, or questions, feel free to ask

There is this nice saying "we learn from our mistakes".
I still remember the first time Linus ripped apart one of my patches. I learned something that day.

Well, doing 8 versions of one patch set a day is obviously the other extreme ;) For example, there is this unwritten rule to wait ~1 week (and before discussions slowed down) before sending another revision. There are exceptions of course.
In general, we're lacking reviewers, not code contributors. So we really need people that can get familiar with the code and gain expertise, to help the project long term.
Drive-by AI generated patches that mostly just consume more of the precious maintainer+reviewer time are rather counter-productive.

I think you had some patches accepted my maintainers, you might want to consider reaching out to them to see if they would be willing to help.
But be aware that most people are extremely busy.

And yesterday we got another sloppy posting, so that would be it for having some time off to learn things and take slowly. 3 days after this AI slop which does not even build.

and it was a genuinely "ok" patch.
May you please tell me what I did wrong here.
I thought you wanted to "take a couple months break"? And I suggested getting a mentor first.
Yeah, that again, was a bit stupid of me, but sorry for breaking my break, but I wanted to try doing a human patch, to see if I am capable

Anyhow, this mail was sent from "Herbert", which is quite ... confusing.
Changed, it was a display name for some reason.

We've heard enough of your excuses that look less and less plausible. Just go away at this point, please.

Hello david, thanks for being polite about this whole thing!
so, you are talking to a real human, i promise you that now
That's exactly, what I would say if I were a bot ;)
Well, I don't know what else to say. I have matrix and irc I guess, I can prove I'm human

As a first step, fix the line wrapping. The following document was helpful to me in the past:
Documentation/process/email-clients.rst
Yeah.. mobile clients hurt me, I tried thunderbird and it didn't come with word wrapping (I was a bit angry at that), I am mostly away from my pc, (the place I do patches!)

I am looking for people to personally mentor me, so i succseed in the kernel
And, I know this is unprofessinal (and im sorry!), but my github is my best
friend, i have a year worth of commits for you to see publicly, also i work with android custom roms. (Any questions, feel free to ask!)

So yes, this is my oppotunity to be honest,
(Yes. I do use AI!)
The reason why, is im a "perfectionist", i want to start human patches, but

im scared i will get ripped apart, (or i wont get like reviewership!! Because im too slow) so i use claude (smartest ai in the market), and i regret it. Like seriously!
There is this nice saying "we learn from our mistakes".
I still remember the first time Linus ripped apart one of my patches. I learned something that day.
Exactly! Mistakes happen, you learn from them, (I was stupid for breaking my break...)

Additionally, i hate being slow, im scared that the community will ditch me
if i do 1 human patch every 2-4 weeks, which is my expected time (because i need to understand the code!!!!!)
Quoted 1 line
Well, doing 8 versions of one patch set a day is obviously the other extreme ;) For example, there is this unwritten rule to wait ~1 week (and before discussions slowed down) before sending another revision. There are exceptions of course.
Yeah, was stupid of me ngl

In general, we're lacking reviewers, not code contributors. So we really need people that can get familiar with the code and gain expertise, to help the project long term.
I sure can review code. I do review code for people who ask for my custom ROM stuff, basically they need kernel trees for it to build and stuff basically.

Drive-by AI generated patches that mostly just consume more of the precious maintainer+reviewer time are rather counter-productive.
Yeah. Very stupid of me

I would love to have a mentor to help me around, and when (if) somebody
wants to, i promise you now, i will start making human patches, and i will benefit the community positively,

I think you had some patches accepted my maintainers, you might want to consider reaching out to them to see if they would be willing to help.
To be fair, Masami is extremely busy, so is seong, Andrew is "Stupidly busy" (his words), which is understandable because he maintains lib/ and some of mm/

But be aware that most people are extremely busy.
