From 833e0e2f24fd0525090878f71e129a8a4cb8bf78 Mon Sep 17 00:00:00 2001 From: Jakub Kicinski Date: Tue, 10 Oct 2017 15:05:39 -0700 Subject: [PATCH] net: dst: move cpu inside ifdef to avoid compilation warning If CONFIG_DST_CACHE is not selected cpu variable will be unused and we will see a compilation warning. Move it under the ifdef. Reported-by: kbuild test robot Fixes: d66f2b91f95b ("bpf: don't rely on the verifier lock for metadata_dst allocation") Signed-off-by: Jakub Kicinski Signed-off-by: David S.
