You can't just say "general GPL issues aside".  Honestly, given your
company's prior actions in regards to Linux kernel drivers and the
licenses of them, I don't trust them at all.  To help gain that trust
back, marking the exports in this manner will be a great improvement.

To insist otherwise is to only reinforce my doubts, and reduce my
wanting to even review or accept this code at all.  Sorry about that.

What other calls can be removed?  Did you run sparse on all of these
files to ensure that things are "clean" with regards to static functions
and the like?
