Any future change in this kernel header will require a change in this 
check as well and also a commit into fixup-include/rdma-ib_user_verbs.h 
with the new kernel code, correct ?

How will people be aware of that and won't miss it ? can we have some 
script that will warn/suggest the expected change upon a kernel change ?

Yes.

Keeping the header up to date is not a big problem, there is no way to
get new symbols otherwise so people patching in new features have to
do it.

travis always does compiles using these headers as well.

Keeping the check quoted above broadly correct is more difficult. I
can't think of how to automate that, other than to manually inspect
patches that update the header to make sure they update the check as
well.

We could also switch to a more iproute like model where we just
unconditionally use our copies of the kernel headers..

Are you referring to drop the cmake linux header check and always use a 
private copy of the latest kernel UAPI file in rdma-core ? it can make 
more sense comparing to current candidate code.

It can reside in a folder named 'rdma' and not installed by rdma-core as 
applications don't use this file. If so we can drop the fixup file and 
its matching check.

What do you think ?

It seems worth doing now, but not as part of this series

OK, so let's go ahead, merge the series and do that just later with some 
refactoring series to have the solution as part of this rdma-core release.
