From 41b02ea4c0adfcc6761fbfed42c3ce6b6412d881 Mon Sep 17 00:00:00 2001 From: "Matthieu Baerts (NGI0)" Date: Wed, 5 Jun 2024 11:21:16 +0200 Subject: [PATCH] selftests: net: lib: support errexit with busywait If errexit is enabled ('set -e'), loopy_wait -- or busywait and others using it -- will stop after the first failure. Note that if the returned status of loopy_wait is checked, and even if errexit is enabled, Bash will not stop at the first error.
