Good catch, applied, thank you!

I reworked the commit message as follows, so could you please check
to make sure that I didn't fold, spindle, or otherwise mutilate

						Thanx, Paul


commit 0848a1dfea913f0c384b49a1f61f84b95a4d555a

    torture: Remove exporting of internal functions
    The functions torture_onoff_cleanup() and torture_shuffle_cleanup()
    are declared static and marked EXPORT_SYMBOL_GPL(), which is at best an
    odd combination.  Because these functions are not used outside of the
    kernel/torture.c file they are defined in, this commit removes their
    EXPORT_SYMBOL_GPL() marking.
