Re: [PATCH -next v2 3/5] selftests/cpu-hotplug: Delete fault injection related code

[zhaogongyi]

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/20220905133615.139026-4-zhaogongyi@xxxxxxxxxx/

Thanks for your review!

Kind regards,
Gongyi
