On embedded platforms, the CONFIG_KALLSYMS compilation option may not be enabled due to reasons such as reducing the size. This will cause the test item to fail. Do you still insist on returning a test failure when the opening fails? > Why aren't you waiting for the thread right here?

Also for the reasons mentioned above, my idea is to ensure that the test item can pass with a high probability even if the CONFIG_KALLSYMS option is not enabled. Thank you very much for your patient guidance. I was quite busy some time ago, so I'm replying to you now. I'm really sorry. Thanks
