> what should they do?

Sorry to ask, but couldn't it be solved with cargo? I hear all the time about the benefits of Rust tooling and zero-cost abstractions.

Why can't a driver just pull/include the latest-dma-bindings crate and glue the gap with zero-cost abstractions?

If kernel DMA code/API changes, then nothing breaks in the kernel (hopefully) and the "Rust devs will quickly solve the changes" theory can be really proven and tested by quickly updating the bindings AND the updating the drivers.
