It should set config->test_fs instead of config->test_driver as NULL after kfree_const(config->test_fs) to avoid potential double free.

I suggest to improve this change description.

• How do you think about a wording variant like the following?

  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.

• Would you like to add the tag “Fixes”?

Regards, Markus

OK, I will send a v2 patch with the updated commit message and "Fixes" tag.
