That's why I had some doubts! I didn't study this enough, but my
(older) version definitely showed hz == 100. Maybe I'm wrong, but
looking into lib/util.c it seems this could be set differently
depending on system's configuration (or even kernel version).
So, probably this patch could sometimes work even for HZ < 1000,
but since it's your patch, I hope you do some additional checking
if it's always like this...
Cheers,
