From a4393861a351f66fef1102e775743c86a276afce Mon Sep 17 00:00:00 2001 From: Jakub Sitnicki Date: Mon, 17 Feb 2020 12:15:28 +0000 Subject: bpf, sk_msg: Let ULP restore sk_proto and write_space callback We don't need a fallback for when the socket is not using ULP. tcp_update_ulp handles this case exactly the same as we do in sk_psock_restore_proto. Get rid of the duplicated code.
