Ok, if this is true, can someone provide me with a working backport of
this patch?  As it is, it does not apply cleanly, and I don't know how
to resolve the merge error.

Or, we can just not worry about it, as I'm only going to do one more
4.10-stable release, this week, before we throw it away and never care
about it again :)
