 initialized after each and every call to kmem_cache_alloc(), which renders
 reference-free spinlock acquisition completely unsafe.  Therefore, when
 using ``SLAB_TYPESAFE_BY_RCU``, make proper use of a reference counter.

 With traditional reference counting -- such as that implemented by the
 kref library in Linux -- there is typically code that runs when the last
