it's not clear if that means that it was a *one-time* transition
aid which is now unnecessary, or whether it's an *ongoing* aid which
might be used at any time. currently, there are no invocations of
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.

ok, so maybe its removal file entry should be deleted if it's going to
hang around. your call.


the removal entry is/was for the symbols *marked*, not for the infrastructure....
