Subject: Re: [PATCH v4 4/4] selftest: Taint kernel when test module loaded
Hi David,
I love your patch! Yet something to improve:
[auto build test ERROR on masahiroy-kbuild/for-next]
[also build test ERROR on shuah-kselftest/next linus/master v5.19-rc4 next-20220701]
[cannot apply to mcgrof/modules-next]
[If your patch is applied to the wrong git tree, kindly drop us a note.
