Ah, I had not realized that the other patch was still in ipvs-next
and not merged in mainline. I did most of my testing on linux-next
(with the previous patch) and then validated the new one on
4.5-rc1, which led me to update it to contain the same hunk again.

Replacing the original patch works fine though, thanks for picking
it up!
