You've submitted this exact same patch before and Greg asked a couple of
questions about it: https://lkml.org/lkml/2013/1/25/599

If this is a resubmission, then it would sure be nice if that was clear
from the subject and on. And I believe any previously asked questions
should be answered in some way. I see that you have responded to one of
them by moving part of the commit message to the cover letter, but still
without any answer to the question.

To me this looks like you completely ignored Greg's review questions. Is
that so?
