Oh, I see, yes. You're thinking of a case where multiple protocols support this destroy operation. An in-kernel caller has a pointer to a sk that it wants to unwedge, but doesn't need to know which destroy function to use for which protocol, it just does "if (sk->sk_prot->destroy != NULL) sk->sk_prot_destroy(sk)". I think that should be a trivial change on top of what I have. -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
