If kunit_filter_suites() succeeds, not only copy but also filtered_suite and filtered_suite->test_cases should be freed.
So use kunit_free_suite_set() to free the filtered_suite, filtered_suite->test_cases and copy as kunit_module_exit() and kunit_run_all_tests() do it.

Hello!
This looks mostly good to me. But I have one notable comment. See below.
Thanks! -Rae

I definitely appreciate the change to free all of "got" rather than just "got.start".
However, kfree_at_end used deferred actions to ensure the kfree would occur at the end of the test. With this change, if the test fails the suite set could not be freed.
Intead, is there any way to alter the function kfree_at_end (could be renamed) to take in "got" and then use deferred actions to ensure kunit_free_suite_set is called at the end of the test?
Let me know what you think about this.
