Right. I didn't remember that I merged that over your NAK but I don't
share your view that kmem_cache_destroy() callers should do
rcu_barrier() or whatever is necessary if we can do it from
kmem_cache_destroy(). So I am happy to take both changes but I would
appreciate them being split into two separate patches.
