Explains static CPU isolation using nohz_full, isolcpus and rcu_nocbs and why that model wastes resources in containerized, dynamic workloads. Describes dynamic CPU isolation in the Linux kernel — creating and releasing isolated CPUs on demand — and covers which kernel background activities have already been offloaded dynamically and which still require work to match static isolation.
