The kernel is not CH's project. It's not his call to reject things he doesn't like anywhere in the kernel, including places he doesn't personally maintain.

Since Linus backed him up on this issue I’m left with the impression that Christoph is not a lone maintainer standing in the way of the inevitable march of progress; that his concerns are valid and shared by the founder and leader of the project and represent the views of other maintainers who preferred not to step into the ring on this debate.

Furthermore, the Rust code depends on his C dma code. That automatically makes it Christoph’s problem when something breaks, regardless of how many R4L maintainers come and go from the project.
