From c66fb480a3302577f657a5d4f5308312bf1b52f8 Mon Sep 17 00:00:00 2001 From: "Matthieu Baerts (NGI0)" Date: Wed, 6 Mar 2024 10:43:01 +0100 Subject: [PATCH] selftests: userspace pm: avoid relaunching pm events 'make_connection' is launched twice: once for IPv4, once for IPv6. But then, the "pm_nl_ctl events" was launched a first time, killed, then relaunched after for no particular reason. We can then move this code, and the generation of the temp file to exchange, to the init part, and remove extra conditions that no longer needed.
