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."

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.
-
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 isn’t this in specific just about bindings?
-
Yeah that is a very opinionated description. Up until “the submitter became very angry, lashed out” 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. It’s not exactly an objective view, whatever that’s worth.
-
The part where I exclusively stated facts is opinionated?
-
Isn’t it just to make the code more idiomatic rust side? If there’s breaking api change c side, it’s just a matter of adjusting the interface, it should not involve any grand work, right? The contributor bringing that change over can just ping anyone familiar with the rust interface and that should be the end of it for them, can’t imagine it’d be very involved to fix
-
Submitter becoming very angry is not an objective view of it, unless you know for a fact they did become not only angry or frustrated, but very angry. Which would still be very leading because of the use of “very” where not necessary. Lash out on someone/something is also a very leading choice of words, since it has connotations beyond the neutral.
I’m just saying a lot of subjectivity on the words chosen, and that others should be aware.
-
He was using charged language and ultimately wrote a long rant about failed leadership and resigned from the project he founded as a result. I don't know how you can possibly interpret that any other way.
-
Marcan was probably fed up and was looking for a reason leave. If that's not the case, then it's silly for him to just quit mid-discussion, before it's even become apparent what the reaction to Cristoph Hellwig's behavior would be and whether his reply would even be taken into account during the review process.
-
Yeah, that’s exactly what it is, as you say: Your interpretation. Can’t offer much more as a third party, and I’m not saying it’s wrong or anything, I was just bringing the fact that it is a subjective interpretation up, since it probably isn’t clear for everyone.
“Long rant about failed leadership” is probably not how everyone would describe it/them, either. And just the use of “rant” there, as opposed to something neutral like “a post” or “writing” or whatever, is an example of what I mean. It’s not wrong and doesn’t imply you are wrong, but it is suggestive. Which, again, is fine, I do not understand why not just let the quick note I dropped be, rather than try and fight it for no reason
-
before it's even become apparent what the reaction to Cristoph Hellwig's behavior would be
It was very clear that the reaction was going to be no reaction. That's the point.
-
Because the "quick note" you dropped is wrong. There's no defensible position where his reaction can reasonably be interpreted as anything else.
-
Marcan is not the submitter. Unless I've missed something, the submitter is still working on the patch.
-
Yes you're correct. I'll update that.
-
So you dictate the objective truth in situations where there are but interpretations? Any other interpretations are wrong, with a bold font even, other than yours, which you solely deem correct?
Right. I mean this is exactly what I was just dropping in to signal. And it’s not about who or what is right or correct. It’s the use of leading words… that’s all. Jesus.
-
Any other interpretations are wrong
Yes that's what I said.
