It depends what they mean by some of these: are the state machine race conditions logic races (which Rust won’t trivially solve) or data races? If they are data races, are they the kind of ones that Rust will catch (missing atomics/synchronization) or the ones it won’t (bad atomic orderings, etc.).
It’s also worth noting that Rust doesn’t prevent integer overflow, and it doesn’t panic on it by default in release builds. Instead, the safety model assumes you’ll catch the overflowed number when you use it to index something (a constant source of bugs in unsafe code).
I’m bullish about Rust in the kernel, but it will not solve all of the kinds of race conditions you see in that kind of context.
