He literally did not. He literally explicitly said right there in the (in)famous "cancer" message that it didn't refer to Rust as a language.[1]
"And I also do not want another maintainer. If you want to make Linux impossible to maintain due to a cross-language codebase do that in your driver so that you have to do it instead of spreading this cancer to core subsystems. (where this cancer explicitly is a cross-language codebase and not rust itself, just to escape the flameware brigade)."
Stop spreading this kind of misinformation.
And no, I don't think he came off very well here, but please, give it a good faith reading.[2]
care to explain why the following patch that touches nothing got rejected?
rust/bindings/bindings_helper.h | 1 +
rust/kernel/dma.rs | 271 ++++++++++++++++++++++++++++++++
rust/kernel/lib.rs | 1 +
rejecting such patch is the exact cancer that need to cured. stop misleading people.
The reason patch got rejected is super simple: because this wrapper not lives in specific driver and depends on DMA subsystem internal API.
And this cause problem. When someone make any change to Linux kernel they suppose to fix all the code they break across all kernel. And if said wrapper accepted then maintaner of DMA will have to make sure that all patches he accepts also fix Rust parts.
So he just dont want extra burden for himself.

if multiple rust based drivers all need to have DMA support, what should they do? each come up with their own little magic?

this has been explained like 10+ times in this thread - it was made crystal clear to the DMA maintainer that he/she doesn't need to maintain the rust stuff, it is totally okay to break it.
> So he just dont want extra burden for himself
he can just resign. simple and period. no one is ever forcing him/her to be the maintainer when he/she is literally forcing other people to stop developing Linux support for the only powerful & affordable ARM machine for home use.

No, he didnt refer to Rust as cancer, but to Rust in the Linux kernel / the R4L project.
