> Any normal Rust kernel will either have issues scaling on multi-cores or use tax-heavy synchronisation primitives. The kernel RCU and lock-free algorithm took a long time to be discovered and become mature and optimised aggressively to cater for the complex modern computer architectures of out-of-order execution, pipelining, complex memory hierarchies (especially when it comes to caching) and NUMA.

Why would that be the case at all? What has Rust anything to do with that?
