I am not sure what you mean here, but just to clarify: our goal is to
improve Linux with Rust, not to increase its adoption (even if
obviously many of us would like that). And just in case, it is not
"our" language either -- most of us do not come from upstream Rust.

In general, we do try to make things as familiar as possible, but
sometimes it doesn't make much sense, so we don't follow C blindly.

For instance, C23 also got checked integer arithmetic macros, but that
doesn't mean we should start using names like `ckd_add`, returning
booleans and, worse, using macros for those. C23 also got `nullptr_t`
-- similar story.

Cheers,
Miguel
