No, I think it's right. Looks like you are expecting other problems,
like mentioned in patch 6, to be fixed by this patch.

Noted that this patch just fix one case that MD_RECOVERY_RUNNING can't
be cleared, I you are testing this patch alone, please make sure that
you still triggered the exactly same case:

- MD_RCOVERY_RUNNING can't be cleared while array is suspended.

Thanks,
Kuai
