The sunrpc module uses rcu_call() thus it should use rcu_barrier() on module unload. Have not verified that the possibility for new call_rcu() callbacks has been disabled. As a hint for checking, the functions calling call_rcu() (unx_destroy_cred and generic_destroy_cred) are registered as crdestroy function pointer in struct rpc_credops. Acked-by: Paul E.
