Simon Horman says:

====================
Fourth Round of IPVS Updates for v4.4

please consider these build warning cleanups from David Ahern and myself.
They resolve some minor side effects of Eric Biederman' heroic work to
cleanup IPVS which you recently pulled: its queued up for v4.4 so no need
to worry about earlier kernel versions.
