From a277d516de5f498c91d91189717ef7e01102ad27 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Fri, 2 Nov 2018 16:36:55 +0100 Subject: [PATCH] openvswitch: fix linking without CONFIG_NF_CONNTRACK_LABELS When CONFIG_CC_OPTIMIZE_FOR_DEBUGGING is enabled, the compiler fails to optimize out a dead code path, which leads to a link failure: net/openvswitch/conntrack.o: In function `ovs_ct_set_labels': conntrack.c:(.text+0x2e60): undefined reference to `nf_connlabels_replace' In this configuration, we can take a shortcut, and completely remove the contrack label code. This may also help the regular optimization. Signed-off-by: Arnd Bergmann Signed-off-by: David S.
