Hi Shiyang,

I'd like to merge this patchset now, but I just noticed these 3 new cases
doesn't have Copyright announce, so I hope to double check with you that
if you intend to drop Copyright line?

If so, I'll merge directly, or please tell me what Copyright do you want
to use, or send a new version with your Copyright (and RVB from Darrick).

Thanks,
Zorro
