Linus responds to Hellwig - "the pull request you objected to DID NOT TOUCH THE DMA LAYER AT ALL... if you as a maintainer feel that you control who or what can use your code, YOU ARE WRONG."

Hellwig is the maintainer of the DMA subsystem. Hellwig previously blocked rust bindings for DMA code, which in part resulted in Hector Martin from stepping down as a kernel maintainer and eventually Asahi Linux as a whole.
Linus ain't wrong tho

Gee Linus you think you could've fucking said something before it got to this point?

Anyone got more context on this I can read through? I haven't kept up with this other than Linus's notorious attitude.

It's mostly in that linked thread. The high level of it is a guy wanted to push Rust code. The maintainer said no it would mean the API for this would be tied to Rust and that is unacceptable. It cause another big contributer to throw a fit and Linus said he can't be everyone's mom. They kept fighting for like 2 months apparently? Now Linus stepped in, looked at the code and said the Rust code clearly doesn't impact the API in the way the maintainer was saying it just breaks itself if the maintainers allow changes to the API.
I kinda dislike the idea that it's cool for people to contribute code that is so easy to break. I have a feeling after it happens a few times they are going to claim that it is being done intentionally and that the slap fights will carry on.

I do not know why you say it is easy to break.
The Rust team are maintaining their side. I do not expect it to break. And the C code that the Rust code depends on is used by lots of other code. It should be a stable interface. Changing the C code just to break the Rust code would break a lot of C code too and upset a lot of folks.
And the who point is to create a more idiomatic interface on the Rust side. So, even if the c interface does change, it may only be a small amount of Rust code that needs to change in response.

He is totally correct and it is great to see him finally step in to settle this drama. Hopefully it will reduce the level of noise going forward.

Actual Linux news rather than "which distro should I use for gaming and bit torrents?"

It literally wasn't about Rust specifically though. Christoph literally said it was about anything that was not C, including assembly, C++, brainfuck, or whatever, entering the kernel. Christoph likes Rust. Christoph (rightfully) does not like mixed language codebases for projects as large and important as Linux

God damn if these Rust glazers are so offended by this, just go work on Redox

Sometimes when you're celebrating someone's judgement, don't shit on their judgement.

Thanks for the summary, I did a bit of reading myself. It's interesting the dynamics at play here - you've got a long, long term contributor in Hellwig who's been a maintainer since before Rust even existed, then you've got quite a few people championing Rust being introduced into the kernel. I feel like Hellwig's concerns must have more to do with the long term sustainability of the Rust code - like will there be enough Rust developers 10, 20, 30 years down the line. I mean, even if it stays maintained, having multiple languages in a codebase increases complexity and makes it harder to contribute. Then you have Filho resigning from the Rust for Linux project, which in itself kind of calls into question the long term sustainability of the project. It seems like Rust would have quite a few benefits for the Linux kernel, but the question remains of if it's still gonna be any good in a few decades. This is juicy stuff!

Someone submitted some code to the Linux kernel. One of the maintainers repeatedly denied it for no reason other than it contained code that is not C. The submitter became very angry, lashed out publicly on social media, then removed themselves from the project. They were also the founder of Asahi Linux and resigned from that as well.
It's nothing to do with Rust, specifically.

Yes but that clearly was not happening. And now they lost a contributor for no reason.

And the who point is to create a more idiomatic interface on the Rust side. So, even if the c interface does change, it may only be a small amount of Rust code that needs to change in response.
I can understand Hellwig's fear, though.
From what I gather as a bystander, it's apparently common that a refactoring in your module that breaks its API will involve fixing all the call-sites to keep the effort on the person responsible for the change. Now the Rust maintainers say "it's fine; if it breaks, we'll deal with it" which is theoretically takes away the cross-language issue for the C-maintainer. Practically I can very well see, that this will still cause friction in the future.
Let's say such a change happens and at that time there's a bit of time pressure and the capacity on the rust maintainers is thing for whatever reasons. Will they still happily swallow that change or will they start to discuss if it's really necessary to do that change? And suddenly, the C-maintainer has a political discussion on top of the technical issue they wanted to solve.
As someone who just wants to get shit done, I would definitely have that fear.
(That doesn't mean it's still a bullet not worth swallowing. The change overall can still be worth the friction. I am just saying that I think it's not totally unwarranted that a maintainer feels affected by this even though current pledges from the other parties promise otherwise; this stance can change or at least be challenged over and over.)

But isnât this in specific just about bindings?

Yeah that is a very opinionated description. Up until âthe submitter became very angry, lashed outâ that sounds about right, but from there on, your bias shows. Which is fine, and human, but probably worth mentioning this to others reading this. Itâs not exactly an objective view, whatever thatâs worth.
