There is a test written to test compilation of exported kernel headers
one by one in userspace. lkml thread is here:

https://lkml.org/lkml/2015/2/16/521

The series should have gone to the right addresses with:

$ git send-email --to linux-kernel-u79uwXL29TY76Z2rM5mHXA@public.gmane.org \
	--cc-cmd "scripts/get_maintainer.pl --norolestats"

I have no idea where the rest of this series went (neither netdev, nor
lkml, nor linux-sctp) and what user space application making use of the
header you are trying to fix !?

Looks ugly, but could also be resolved in user space.
