Hi shuah,

I am so sorry! There are some mistaks in the patch that did not delete the config file, please skip the patches of v2 version. And I have resubmit the patches with new version, please see: https://patchwork.kernel.org/project/linux-kselftest/patch/20220905133615.13...

Thanks for your review!

Kind regards, Gongyi

Delete fault injection related code since the module has been deleted.
