Merge branch 'skb-accessor-cleanups'
Johannes Berg says:
====================
skb data accessors cleanup
Over night, Fengguang's bot told me that it compiled all of its many
various configurations successfully, and I had done allyesconfig on
x86_64 myself yesterday to iron out the things I missed.
So now I think I'm happy with it.
My tree was based on your
commit 3715c47bcda8bb56f7e2be27276282a2d0d48c09
Merge: 18b6e7955d8f d8fbd27469fc
Author: David S. Miller <davem@davemloft.net>
Date: Thu Jun 15 14:31:56 2017 -0400
Merge branch 'r8152-support-new-chips'
when the compilation tests happened, but I've reviewed the changes
coming into net-next in the meantime and didn't see any new usages
of skb data accessors having come in.
