Given that this commit did not change rcutorture or anything that
rcutorture invokes, I am having difficulty seeing how it caused
this failure.  Or am I missing some indirect series of inline function
invocations?

Easy enough to add the EXPORT_SYMBOL_GPL() if it is needed!  ;-)

							Thanx, Paul
