Subject: [PATCH net-next 0/5] generic net and ipv6 minor optimisations

1-3 inline simple functions that only reshuffle arguments possibly adding
extra zero args, and call another function. It was benchmarked before with
a bunch of extra patches, see for details

It may increase the binary size, but it's the right thing to do and at least
without modules it actually sheds some bytes for some standard-ish config.
