Is there an easier way forward for rust in linux? (programming.dev)

Every week or so there seems to be drama about some old dude shouting about how rust in the Linux kernel is bad. Given all the open hostility, is there easier way for R4L to continue their work?

it’s only additions like new drivers.

What prevents them from rewritting old drivers? Some sort of API incompability? I was under the impression they were doing just that.

I think the biggest issue would be a lack of interfaces to the C side code, they're slowly being fleshed out and each one enables more functionality for the Rust modules.

e.g. the test Ext2 driver a MS dev wrote last year after enough of the filesystem interfaces got hooked up

But even then, I don't think the maintainers would accept one that replaces the existing C driver, that'd break non-Rust builds and architectures, and that's a sure-fire way to get Linus on your case. Best you can hope for is one that complements a C driver, and even then I think you'd need a good reason to have two drivers for the same hardware.
