Just realised something while taking a look at you're schedtop: you are
referring to sched_stats, which shows data in /proc/schedstat, while my patch
actually targets sched_debug, which shows data in /proc/sched_debug.  And I
guess this is why we have 2 different versioning mechanisms:  they refer to
different things :-)

So, if this is correct, my last patch actually updates the correct version,
right?
