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.
It appears so now, yes, but when the drama initially came out it sounded like they were asking for a tiny amount of rust in the kernel to make it work, or if not rust, changing the C to tailor it specifically to the rust. Which I think is a reasonable thing to be concerned about from a maintainability perspective long-term, especially if the rust developers decide to leave randomly (Hector’s abrupt quitting over this very issue is a prime example).
