[PATCH 3.19.y-ckt 121/164] tcp: call sk_mark_napi_id() on the child, not the listener

From: Kamal Mostafa
Date: Wed Dec 02 2015 - 12:22:39 EST


3.19.8-ckt11 -stable review patch. If anyone has any objections, please let me know.

------------------

From: Eric Dumazet <edumazet@xxxxxxxxxx>

commit 38cb52455c2c3e8b5751350a3fb32e43e82e129a upstream.

This fixes a typo : We want to store the NAPI id on child socket.
Presumably nobody really uses busy polling, on short lived flows.

Fixes: 3d97379a67486 ("tcp: move sk_mark_napi_id() at the right place")
