> Ted Ts'o said that the Rust developers have been trying to avoid scaring kernel maintainers, and have been saying that "all you need is to learn a little Rust". But a little Rust is not enough to understand filesystem abstractions, which have to deal with that subsystem's complex locking rules. There is a need for documentation and tutorials on how to write filesystem code in idiomatic Rust. He said that he has a lot to learn; he is willing to do that, but needs help on what to learn

If he didn't want Rust in the kernel, he would have said it, and there would have been no Rust in the kernel. It is also the reason why there is no C++ in the kernel, Linus doesn't like C++. It is that simple.

And I respect that, Linux is hugely successful under Linus direction, so I trust his decisions, whatever opinion I have about them.
