The C side people read the Rust code before changing the C code? Let's
see. 

Hmm... I usually won't call someone "C side people". I mean, the project
has C part and Rust part, but the community is one.

In case of myself, I write both C and Rust, if I'm going to change some
C side function, I may want to see the usage at Rust side, especially
whether my changes could break the safety, and safety comments may be
important.

While i agree with your sentiment, ideally we want bilingual
developers, in reality that is not going to happen for a long time. I
could be wrong, but i expect developers to be either C developers, or
Rust developers. They are existing kernel developers who know C, or
Rust developers who are new to the kernel, and may not know much C. So
we should try to keep that in mind.

I personally don't think i have enough Rust knowledge to of even
reached the dangerous stage. But at least the hard part with Rust
seems to be the comments, not the actual code :-(
