The agent helps a lot to fix bugs. Just point the agents at the bug reports. They do the reproduction, debugging and fixes. We "just" have to review. (Sometimes ask more details and tell we'd prefer another approach.) This makes bug fixing much faster and automated.
And at the same time, it seems we get less bug reports to our library.
I think user just use their agents to code, and agents don't report bugs, they just work it around somehow.
So overall, the open bug count is decreasing. Which somehow feels good.
On the other hand, we get a lot of PR made by other's people agents, which can be a bit overwhelming when it's just a huge code drop. We can't easily review that.
> > and agents don't report bugs, they just work it around somehow.
Yeah I've definitely noticed this. On a project I'm working on Opus 5.5 found a bug in Smithay and another in Winit. It did tell me about them but its preferred solution was just to work around them locally. To be fair we don't really want agents going off and reporting bugs automatically...
I don't run any big open source projects but I think my preferred solution to AI PRs would be to get my AI to implement the same thing, and give then afterwards tell it to look at the PR for anything it missed. Then I at least know that I'm using a competent model and it reduces the danger of just blindly accepting someone else's code. (And obviously review the code if you have time and care, but that isn't always the case.)
Yes the default behavior of working around the bug is good, that’s what everyone was doing anyway pre-LLMs. The good practice is to report the bug. Simply add instructions to your agents to report you the bugs it found in the summary, so you can check the bug and report it correctly upstream.
>I think user just use their agents to code, and agents don't report bugs, they just work it around somehow.
Claude comes up with some truly delicious insane workarounds these days. Like launching something in a subprocess and capturing stdout/stderr and doing string parsing on info logs because of a desire for some hook not exposed by API (or at least that it didn't find on its quick scan).
There's probably no such thing as semver reliability for dependencies anymore in stuff that agents glue together, since they will poke at ANY sort of way of getting additional insight or control if they want it.
also the agent might introduce bugs, just like a human (see rsync which now has very busy development). Likely we (and the LLM) just won't notice them as easily. Fun times I guess.
Not quite. My C++ Linux rewrite is already production ready, meaning in theory I no longer need to rely on the Linux kernel devs. This will, in a matter of months I presume, become the norm.
The headline is "Development statistics for the 7.2 kernel", and the last paragraph is highly LLM critical in contrast with the editorialized headline "Linux bugs fixed per release over time: >2× rise since 2026-04", which seems to imply some sort of Mythos bug finding.
From the last paragraph:
"The Linux kernel is aimed at production use, not research or experimentation. But there is currently a massive experiment being run on the kernel's development processes and community."
"This community has absorbed new processes and tools many times over its 35-year history, and will almost certainly find a way to do that this time as well. But that absorption has not always been without turbulence along the way."
The major issue with these kinds of blurbs is that there's no control.
Historical numbers are not valid because incentivizes of a well funded entity have changed. It would require an equally well funded push to up the patch numbers without LLMs to really measure the impact in a quantifiable way.
So it seems worth vibecoding a survival analysis for bugs introduced. But not quite a survival analysis because we don't even know the bugs exist until the event of their discovery.... Is there a publicly available dataset for this, with a URL?
Heads up for those upgrading to 7.3, I just downgraded my slackware box from 7.3-rc7 to 7.2.10 because /dev/input/events was missing. Keyboard and mouse only worked in the console as a result.

To the surprise of no one. Although, I must recognise that I did not envision a future where Linus embraced AI as frictionless has its been, then again after the inclusion of Rust in the kernel, I probably would've risked some money on it.
I’m strongly with you on that. Current models aren’t perfect, but neither am I. In a lot of my daily use, they’re as good as or better than I am at certain tasks.
I hear people around me talking about a bad experience they had with ChatGPT last summer as though it proves all AI coding is “slop”. Honestly, it makes me sad for them. There are reasons to dislike AI, but so many detractors skip right past those to anecdata that just aren’t relevant anymore, if they ever were.
Current models are still worse than I am, or any competent developer I've ever worked with. You act as though people tried ChatGPT in 2023 and gave up forever, but that isn't what is happening here. The cold hard truth is that, contrary to what AI boosters claim, LLMs still suck at programming and output slop.
Or, he has a full understanding that, like everything single thing he's ever been involved with in his career, it's a new tech under development and will, as every measure up to now has demonstrated, improve over time. And, as all tech that has ever existed since the beginning of man starts, has somewhat initially limited, but still very practical and real, use in its current state.
Again, he's pragmatic, and has seen countless types and iterations of tech come into existence. The people expecting perfection from the start have no actual experience with the creative process, engineering or design, and and only want progress to stop (because there is, literally, without exception ever existing, no alternative to iteration).
Yes, Linus is quite forward thinking, and we can credit that with why Linux has stayed relevant for so many decades. Not many software projects manage to pull that off.
Linus has always been pragmatic as opposed to dogmatic.
20 years ago he was fine using BitKeeper, proprietary software, for kernel source control, because it was better than Subversion and CVS. He only created git when BitKeeper introduced some road blocks.
While great in theory, the flip side is all the slop patches and PRs that both the kernel and open source in general now has to deal with, often with only agents as responders.
It honestly doesn't want to make me open anything for outside contributions anymore.
He used Claude Code to write one of his patches in [0] and introduced a data race bug in the kernel unbeknownst to himself but this bug was caught by other reviewer [1] before it made it into a new kernel release.
So I'm afraid Linus himself did not understand the changes Claude made to the code he submitted in the mailing list, despite his "principles" in telling others previously that AI was creating slop patches and then now shouting at others who were concerned about using LLMs on code where they do not understand the generated code themselves when it all applied to....himself.
The data race is exactly the kind of subtle bug that even very experienced programmers would make in this circumstance.
The patches that Linus posted are relatively small and self contained and from reading the thread it seems came from a series of in depth conversations with Claude and were carefully reviewed by Linus.
So what we're seeing here is a tricky concurrency bug that even an expert would make. You can't use it as an example of slop
> The kind of expectations I have is that people do their best and I expect people to understand what they are doing.

He’s saying that understanding or competence are more about the person than their AI use. I think that’s a reasonable argument, even though I disagree on the basis that it’s at least a little correlated in the shortcuts in understanding the many devs I’ve seen (not all, but a nontrivial amount) seem to be taking.
To be clear: I believe that it's entirely possible to use LLMs to amplify understanding and competence, but that in practice LLM usage is anticorrelated with understanding and competence. This is about empirical reality, not logical entailment.
As an example, I’m in the process of putting up a patch series to optimize some specific filesystem operations. The amount of boilerplate that has to know to get done is completely unapproachable to an outsider both from the amount of time needed to learn that boilerplate and form it in such a way that maintainers will be happy. Even though I know exactly how the code is working, it bridges that understanding gap but I don’t see how it correlates with incompetence. I may be an outlier but I suspect there’s a huge amount of people who are extremely capable and competent and it’s just that the Linux kernel has so many processes that it’s difficult to onboard into the community without LLM assistance.
The Linux kernel project is not hurting for contributors nor was it prior to LLMs. The processes you describe as roadblocks don’t seem to have been preventing the Linux kernel from getting code contributions. Maybe they don’t need or want more easy onboarding or broader audience?
Presumably the person who's full-time job is staying on top of proposed changes to the linux source tree knows something about this; what are your credentials on the topic?
Linus himself is actually comically incompetent. He only became famous after the Linux kernel took off... decades ago? Since Git, he has made ZERO code contributions whatsoever (not even to the Linux kernel). He doesn't even review code and has his team of capos do it for him. All in all he's no different than the CEO of some tech company, his thoughts on LLMs are no longer relevant (for more lack of credibility, see his stance on Rust, C++, Go)

The point is, new technology arrived that allowed developers to do much more. Existing programmers hemmed and hawed about it because it threatened their egos, making easy what they once found very difficult. But the sensible engineers adopted the technology.
AI may not be deterministic, but on small to medium-sized tasks it produces more correct code, more reliably, faster than a human developer does. By any objective measure, not adopting it is professional irresponsibility.
Nice rhetorical sleight of hand, trying to paint your opponents as ego-driven and senseless. But LLMs are not compilers. They cannot be relied upon to work correctly, and indeed can be relied upon to introduce bugs that a human would never introduce. The situation is different, therefore the reactions are different.
> AI may not be deterministic, but on small to medium-sized tasks it produces more correct code, more reliably, faster than a human developer does.
> AI may not be deterministic, but on small to medium-sized tasks it produces more correct code, more reliably, faster than a human developer does. By any objective measure, not adopting it is professional irresponsibility.
How do you define correctness for any given task? If you know the correct logical process for any given process, writing it in code is just a matter of typing. The issue is that the human author, even when assisted by AI tools, does not know what is the correct algorithm for the task. In most cases, the output is probable code, not correct code.
I believe we are at a crossroads here. The key question is: Do we want (desire or require) humans to understand the implementation?
If the answer is no, then AI agents producing code faster and "more correct" (in some arguably questionable sense but let's fly with the assumption for a moment) should be embraced fully. Take the humans out of the loop, why review code, if there is a problem later then just ask the next AI agent to fix it. Similar to not looking at generated code by a compiler. Iterate fast, don't look back. Some code bases and some entire companies have adopted this view.
If the answer is yes then we need to keep the human in the loop, ensure they have enough understanding to maintain the thing, review all the code etc. AI is just another tool to produce the code which ultimately the human still owns. Many code bases follow this philosophy.
It seems to me that the discussion always ultimately falls on one of these two sides. They are incompatible but you need to pick one. Depending on which you pick, it is easy to predict how you argue in such discussions.
> The key question is: Do we want (desire or require) humans to understand the implementation?
Understanding the implementation is not the root cause here. The actual issue is that all software are built for a particular needs which is human related. In most software, the cost mostly decays to a constant value unless that need has changed or an external event has occurred.
Embracing AI fully is keeping the software in constant flux as it can’t guarantee it will actually follow the requirements and the platform specs. Any prompt has a non zero chance to introduce regressions and breaking changes, disrupting the workflow of the users.
The tools to write the code does not matter to the user just like the hammer does not matter to the person that needs a home. But if your tools results in a badly constructed house that always needs repair and what not, expect complaints.
> Embracing AI fully is keeping the software in constant flux as it can’t guarantee it will actually follow the requirements and the platform specs. Any prompt has a non zero chance to introduce regressions and breaking changes, disrupting the workflow of the users.
You can pin down existing expected behavior pretty well with automated test cases and even bringing formal verification into the mix. Using LLMs to create those, it's not even a major cost factor. Then you are safe from such regressions. Just like when humans make changes. So, I don't see how this is introducing a difference.
> The tools to write the code does not matter to the user just like the hammer does not matter to the person that needs a home. But if your tools results in a badly constructed house that always needs repair and what not, expect complaints.
Indeed. Though I don't see the connection to my point.
the question is about whether you understand in the slightest the output of the tool. does the determinism of the compiler somehow imbue you with a better understanding of the assembly it generates?
> You must have a very weak understanding on this topic
i work on the codegen for a C compiler i'm pretty sure my understanding is better than yours <shrug>
EDIT: and also you've clearly never read that article
> One of the key attributes of a low-level language is that programmers can easily understand how the language’s abstract machine maps to the underlying physical machine
so you did exactly imply "C is a low level language"
The idea that C is a smol language that can be completely understood by one person is one of those myths that need to be put to bed. C is riddled with complexities and footguns, especially but not exclusively around undefined behavior.
UB is basically impossible to avoid in practice--that is why the Linux kernel forced GCC to add a bunch of flags to "do what I mean", making UB defined in those cases.
> The idea that C is a smol language that can be completely understood by one person is one of those myths that need to be put to bed
You don’t need to understand the language completely. You only need to understand the general semantics and refer to the standard and docs to get the semantics down. That’s what they’re here for.
They are also now vibe coding the kernel which is a major issue. Race conditions were already found in one of the slop suggestions. Linus is apparently fine with this degradation in quality.
Who’s vibecoding the kernel? I’ve heard stories of devs using AI to help write code, but don’t recall a single story of an experienced kernel dev vibecoding anything.
I have noticed the same on my project.
The agent helps a lot to fix bugs. Just point the agents at the bug reports. They do the reproduction, debugging and fixes. We "just" have to review. (Sometimes ask more details and tell we'd prefer another approach.) This makes bug fixing much faster and automated.

I usually report the bug and leave a link to it in a comment beside the work-around code.

And? People also introduce bugs. If you are too lazy to setup verification harness, you will be even more lazy to do all testing manually.
Rsync is hopelessly underfunded under staffed. Current developer was forced to takeover, because everyone quit!
> I think user just use their agents to code, and agents don't report bugs, they just work it around somehow.
It's quite a pity, preventing us from improving our model of the domain, from Naurian theory building and presenting a perfected API etc.
Greg KH did a video on the flood of LLM created stuff: https://www.youtube.com/watch?v=NnV_cWeoo5Q , HN thread: https://news.ycombinator.com/item?id=49929391
Which covers how he responds and pushes back on much of this, as well as asking for a patch (not just bug reports)

He's "pushing back on this" because he's being obsoleted in real time.
Oh, you dont have to worry. You'll be obsoleted waaay before him.
Not quite. My C++ Linux rewrite is already production ready, meaning in theory I no longer need to rely on the Linux kernel devs. This will, in a matter of months I presume, become the norm.
This has to be satire
Yes the Linux kernel was in desperate need of a c++ rewrite
Then Linux kernel should be rewritten in FreePascal now.
Pah, that's nothing. I rewrote the Linux kernel in c++ but only using template metaprogramming
My B port is going well. C was a mistake. /s
I can rewrite the kernel in C++ too: update the Makefile to treat .c files as C++. It’ll almost work :)
What is the need for this?

Why? He seems very pragmatic. I fully expected him to embrace it, with the only concern being correctness and quality.
True, but I think there are quite a few very pragmatic people in here, and yet you see the they don't exactly go around singing praises.
You can usually be pragmatic but entirely emotional about something specific. Famously, Linus is both pragmatic AND emotional about being pragmatic.
This is really short-circuiting my brain right now.
The pragmatic ones are excited about where things are going.

It's fascinating how far experiences can diverge. I've had fantastic luck with it starting about a year ago, and it's been rapidly improving since.

You sound like a dinosaur looking at a meteorite.
Also, it took a long time for rust to mature to be considered for linux kernel development. AI is faster but easier to integrate.
As someone who hates c++ so much, he is surprisingly nice to llm.
LLMs write C for the kernel. He would hate them too if they only outputed C++.
100%. Too many people equate LLM assisted programming with vibe coding some slop. Which is just a weird thing to do at this point.
That's exactly why one would expect him to not embrace it. LLM usage is anti-correlated with either of those things.

That is not remotely true.

How do you define correctness for any given task? If you know the correct logical process for any given process, writing it in code is just a matter of typing. The issue is that the human author, even when assisted by AI tools, does not know what is the correct algorithm for the task. In most cases, the output is probable code, not correct code.

The tools to write the code does not matter to the user just like the hammer does not matter to the person that needs a home. But if your tools results in a badly constructed house that always needs repair and what not, expect complaints.

You can pin down existing expected behavior pretty well with automated test cases and even bringing formal verification into the mix. Using LLMs to create those, it's not even a major cost factor. Then you are safe from such regressions. Just like when humans make changes. So, I don't see how this is introducing a difference.

Indeed. Though I don't see the connection to my point.
the question is about whether you understand in the slightest the output of the tool. does the determinism of the compiler somehow imbue you with a better understanding of the assembly it generates?
Yes. If you understand C code well, you have a very good understanding of what will actually happen when the binary is executed.
This is a myth https://queue.acm.org/doi/10.1145/3212477.3212479
I did not say that C is a low level language. You must have a very weak understanding on this topic.
> You must have a very weak understanding on this topic
i work on the codegen for a C compiler i'm pretty sure my understanding is better than yours <shrug>
EDIT: and also you've clearly never read that article
> One of the key attributes of a low-level language is that programmers can easily understand how the language’s abstract machine maps to the underlying physical machine
so you did exactly imply "C is a low level language"
lol nobody "understands C code well"
The idea that C is a smol language that can be completely understood by one person is one of those myths that need to be put to bed. C is riddled with complexities and footguns, especially but not exclusively around undefined behavior.
Undefined behavior is something that you will avoid - of course, only if you know the language pretty well.
UB is basically impossible to avoid in practice--that is why the Linux kernel forced GCC to add a bunch of flags to "do what I mean", making UB defined in those cases.

You don’t need to understand the language completely. You only need to understand the general semantics and refer to the standard and docs to get the semantics down. That’s what they’re here for.
do you want the bugs in your project fixed, no matter the source, or do you want only humans to contribute.
Linus wants the bugs fixed.
They are also now vibe coding the kernel which is a major issue. Race conditions were already found in one of the slop suggestions. Linus is apparently fine with this degradation in quality.
New leadership is needed over there.

Who’s vibecoding the kernel? I’ve heard stories of devs using AI to help write code, but don’t recall a single story of an experienced kernel dev vibecoding anything.
I suppose, feel free to fork the kernel and take the lead?
Come on.

AI fix this, thanks
You can literally do that now. Exactly as you wrote it...
Not good enough, I am testing if some agent is checking hackernews and will fix it for me
