From 79b1b30e4c209c2ff1ddd6559b41dba1dfc8bcd8 Mon Sep 17 00:00:00 2001 From: Magnus Karlsson Date: Thu, 18 Apr 2019 09:21:10 +0200 Subject: [PATCH] libbpf: remove compile time warning from libbpf_util.h Having a helpful compile time warning in libbpf_util.h is not a good idea since all warnings are treated as errors. Change this into a comment in the code instead.
