it's not clear if that means that it was a *one-time* transition

EXPORT_UNUSED_SYMBOL[_GPL] anywhere in the tree. so does that mean
this feature can be tossed? or might it still be used every so often?
it's one of those pieces of infrastructure that get used from time to
time to phase out symbol exports... we should be more agressive about
that; about 1/3rd of the exports is not used by anything in linux, yet
each symbol costs about 100 bytes of memory at runtime.
