Rust and Persistent‑Memory Shift

The Linux 6.18 release highlights a practical pivot: upstream kernel maintainers are accelerating Rust driver integration and adding persistent‑memory caching primitives (dm‑pcache). These changes lower barriers for safer kernel extensions and enable new storage/acceleration architectures that cloud and edge operators can exploit. — If mainstream kernels embed Rust and hardware‑backed persistent caching, governments and industries must reassess software‑supply security, procurement, and data‑centre architecture as these shifts affect national digital resilience and vendor lock‑in.
