From ce71efd03916ea8fe45e9ef6bd6abe4c20734a57 Mon Sep 17 00:00:00 2001 From: Matteo Croce Date: Wed, 30 Jun 2021 18:56:07 -0700 Subject: [PATCH] lib/test_string.c: allow module removal The test_string module can't be removed because it lacks an exit hook. Since there is no reason for it to be permanent, add an empty one to allow module removal.
