It's here:

James has done a fair bit of work on it, but nobody replied to me when I
asked a couple of questions about how the makefile should be modified.
Maybe they just don't want any more help.

Perhaps they got reset when syslog cycled at midnight, or something. :)
Try comparing the number of resets to the number of reads/writes, more like
you would for ethernet collisions. I think that resets will only indicate a
problem when the number of them compared with drive activity is fairly high.
BTW, where did you pull that info from, it doesn't show anywhere under proc
for me.
