Your v3 doesn't include the review tags you got for v2 which makes it
look un-reviewed. See:

  
https://wiki.qemu.org/Contribute/SubmitAPatch#Proper_use_of_Reviewed-by:_tags_can_aid_review

You can either apply them manually by copy and paste when you reword the
commit message or use a tool to apply the old version and collect tags
from the mailing list archive.
