From 4e98ebe5f435fbe5bca91c24bc5d5a2b33025e08 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Thu, 10 Aug 2017 15:23:50 -0700 Subject: [PATCH] test_kmod: fix small memory leak on filesystem tests The break was in the wrong place so file system tests don't work as intended, leaking memory at each test switch. [mcgrof@kernel.org: massaged commit subject, noted memory leak issue without the fix] Link: http://lkml.kernel.org/r/20170802211450.27928-6-mcgrof@kernel.org Fixes: 39258f448d71 ("kmod: add test driver to stress test the module loader") Signed-off-by: Dan Carpenter Signed-off-by: Luis R.
