Effectively, every in-tree classifier (rsvp is the only exception) is making use of call_rcu(). Moreover, moving this into every ->destroy() handler would also be unnecessary overhead, imho, as this is only relevant when we actually _unload_ a module.
+1 indeed unregister_tcf_proto_ops() is only called at module unload time. So there is no overhead from this rcu_barrier(). It's actually mandatory. All modules with rcu callbacks should do that.
