Description

Issue =====
Below modprobe FATAL is got in test_clock_override:

ok 29 - Wait after kill session daemon
  modprobe: FATAL: Module lttng_clock_plugin_test is in use.
  ok 30 - Unique event timestamps with clock override: 1 expect 1

Cause =====
This issue was introduced by the following commit:

commit d267104b87f12ea8f0bf73bff1af272f98dc069e
Author: Francis Deslauriers <>
Date: Tue Sep 15 12:10:18 2020 -0400
Cleanup: use `modprobe --remove` rather than `rmmod`

Modprobe unload lttng-clock-plugin-test before lttng-test
