Oops, yes, sorry, I ran it on a 3.14 backport and then just added
people I found in older patches for that file.

It should, yeah. I haven't tested it (beyond compiling) on master, and
our version doesn't have that code yet, so I can't say for sure.

True. I don't really need the patch to land in a particular release
since we maintain our own tree with backports. It would probably still
be nice if you can get it into the 4.4 LTS to reduce the chance this
will hit anyone again next year.
