    test_kmod: avoid potential double free in trigger_config_run_type() · 0776d123
    Tiezhu Yang authored
    Reset the member "test_fs" of the test configuration after a call of the
    function "kfree_const" to a null pointer so that a double memory release
    will not be performed.
    
    Fixes: d9c6a72d ("kmod: add test driver to stress test the module loader")
