I think you really missed what I was trying to say about the hibernate stuff. May be helpful to reread.
> One of the main Rust spearhead developers felt the need to quit, and almost immediately thereafter Asahi Lina posted an article about how "a subset of C kernel developers just seem determined to make the lives of the Rust maintainers as difficult as possible." By my count that is 0-2.
I again refer you to the article I linked. The drama has greatly subsided and it seems like people are talking through the differences. While there's some unfortunate intransigence (which may have since been clarified btw), there's also a lot of premature eagerness for pushing Rust into Linux. It's a shame for sure that Wedson burned out and left. If nothing else at least 6 months after that departure the conversation tonally is very very different.
> Linus Torvalds admonished the group that he did not want to talk about every subsystem supporting Rust at this time; getting support into some of them is sufficient for now. When Airlie asked what would happen when some subsystem blocks progress, Torvalds answered "that's my job"
> Torvalds pointed out that there are kernel features that are currently incompatible with Rust; that is impeding Rust support overall. He mentioned modversions in particular; that problem is being worked on. The list of blocking features is getting shorter, he said, but it still includes kernel features that people need.
> Brauner said that nobody has ever declared that the filesystem abstractions would not be merged; the discussion is all about the details of how that will happen.
Important to note that the filesystem abstraction conflict is what led to the resignation in the first place. The maintainers are taking a very different position, possibly because of non-public conversations that have happened in the intervening time.
> Gleixner said that, 20 years ago, there had been a lot of fear and concern surrounding the realtime kernel work; he is seeing the same thing now with regard to Rust. We cannot let that fear drive things, he said. Torvalds said that Rust has been partially integrated for two years. That is nothing, he said; the project to build the kernel with Clang took a decade, and that was the same old language.
> As the session closed, though, the primary outcome may well have been expressed by Torvalds, who suggested telling people that getting kernel Rust up to production levels will happen, but it will take years.
It can be frustrating to work on something when the time scale for any kind of observable success can be a decade or more, especially when you see the obstacles as other people on the project. I know I would not have the patience and I'm a huge fan of Rust. Keep in mind that Rust itself isn't actually able to support all the kernel use-cases. There's stuff like which platforms that Rust supports as "tier 1" because the kernel needs to support those platforms - the most likely success case will be having the Rust frontend be able to use GCC as the backend and that work is nowhere near (neither is getting tier-1 automation support for those platforms). Those themselves are years out and so it's understandable that maintainers are trying to figure out how the proposed abstractions will work and how roles and responsibilities will be managed.
> They're not trying to shift the daily work of ~15k developers. They're asking for some shims, stubs, adaptations, and some general flexibility & willingness. They're not expecting everyone to write Rust within the next 18 months.
I mean it's pretty clear that the goal of the "Rust in Linux" project is to stop having any new C code in the Linux kernel. No one is claiming in 18 months but that's clearly the direction and it shouldn't be surprising for there to be an emotional reaction to that, especially from the maintainers who might perceive that as a threat if they only know C, even if that seems illogical to you. And more importantly, maintainers need to do a lot of work and they hadn't signed up to maintain Rust abstractions so there's another emotional aspect of it where they feel someone else is imposing a new environment on them.
