From 31f8b8295bb8997f139fe34b68654f8f1408f0da Mon Sep 17 00:00:00 2001 From: Quentin Monnet Date: Tue, 19 Nov 2019 10:50:09 +0000 Subject: [PATCH] selftests, bpftool: Set EXIT trap after usage function The trap on EXIT is used to clean up any temporary directory left by the build attempts. It is not needed when the user simply calls the script with its --help option, and may not be needed either if we add checks (e.g. on the availability of bpftool files) before the build attempts. Let's move this trap and related variables lower down in the code, so that we don't accidentally change the value returned from the script on early exits at pre-checks.
