patch has severe inlined-as-text corruption, please check
Documentation/email-clients.txt about how to send patches. (or send it
as an attachment, i can process that)

Also, given the extensive feedback from Eric, it would be nice to have
his Acked-by line as well to any patch that is resubmitted for
inclusion, to make sure you meet all the requirements he has outlined.

Thanks,
