Oh, I'm sure not many would have a problem with that.  It's our own risk
management that prevents us from doing that.

Fair enough.

This sounds like one of the options I suggested in the bugzilla bug, but
CONFIG_NFS_FS is the generic kernel definition to enable NFS isn't it?
That would mean that if the vendor's default .config enabled NFS, it
would still not guard the NFSRDMA headers, if I understand you
correctly.

I think you need to invent your own macro (maybe CONFIG_OFA_NFS_FS)
which you define when the user chooses the OFED NFSRDMA and that
definition guards all of the declarations (heck, in most cases, probably
just entire include files, with #include_next <> as the #else case of
the guard) in the OFED NFSRDMA headers.
