This looks like working around the real problem. The test library process is supposed to outlive the child in all circumstances. What exactly happens in your case that this code gets triggered?

If the main process exit without *cleanup() and when the lib process has exit, the test environment would not be reset when the testcase needs resource of device or tmpfs. Signed-off-by: Zhao Gongyi <zhaogongyi@huawei.com> --- lib/tst_test.c | 2 ++ 1 file changed, 2 insertions(+) -- 2.17.1
