I have investigated the first issue but still have no idea about it. According to source code, everything should be OK. The r8169 driver has invoked INIT_WORK(&tp->wk.work, rtl_task) to initialize the work item, so it shouldn't trigger the warning. Have you found this issue in other test cases? Regards!
