For what it's worth, this change appears to fix my issue in preliminary
testing. I haven't actually brought it up on a production machine with a
GRE tunnel that actually works, but the sequence of operations on my
test machine that used to reliably oops no longer does so.
(I tested this against both a quite recent upstream git pull and the
current Fedora 22 kernel source with this patch blindly shoved in on top
by just running 'patch'.)
