From 69b09175d68241cb96ff9433d8e7a17382d720d6 Mon Sep 17 00:00:00 2001 From: Stanislav Fomichev Date: Wed, 6 Mar 2019 15:25:26 -0800 Subject: [PATCH] selftests: bpf: test_progs: initialize duration in singal_pending test CHECK macro implicitly uses duration. We call CHECK() a couple of times before duration is initialized from bpf_prog_test_run(). Explicitly set duration to 0 to avoid compiler warnings.
