Please stop wasting our time by trying to make changes that have
already been rejected. I gave you good reasons last time for why we
aren't going to make this change in XFS, and now you've forced
Darrick to waste time repeating all those same reasons. You did not
respond to my review comments last time, and now you are posting
more patches that make the same rejected change.

PLease listen to the feedback you are given. Indeed, please respond
and acknowledge that you have read and understood the feedback you
have been given, otherwise I'll consider anything from this email
address as "just another annoying bot" and killfile it.

-Dave.
