Free objects will get into per-cpu quarantine if enable generic KASAN. If a cpu is offline and users use kmem_cache_destroy, kernel will detect objects still remain in the offline per-cpu quarantine and report error. Register a cpu hotplug function to remove all objects in the offline per-cpu quarantine when cpu is going offline. Set a per-cpu variable to indicate this cpu is offline.
