The patch itself isn't the problem, it's at the end of the patchset
and easily dropped.  The problem is that you pinged me off-list to try
and get me to move your patchset up the review queue, which isn't
something I appreciate, especially when the feedback I provided
previously was not acted upon ... and yes, I've heard your arguments
about why you continued to carry the patch, but please understand when
I explicitly say "no thank you" to a patch, I want you to drop that
patch; "no thank you" shouldn't be ambiguous.

To summarize:
1. Don't ping me off-list to review patchsets.  I personally find that
incredibly annoying and it guarantees that the patchset gets pushed to
the end of the list (spiteful? sure, but it helps soothe the jagged
nerves of this haggard maintainer).
2. Take maintainer feedback seriously.  If you ignore feedback,
providing a proper review tends to be a waste of time; there are
plenty of other patchsets with authors who are receptive to comments.

Anyway, go enjoy your weekend and just do better next time.  What's
done is done.
