So it seems I need to fold patch2 and patch3 into one patch. Previously
I thought the counters overflow on 32 bit platforms was a bug, thus
I split the 64bit stats patch into patch2 and patch3 so that patch2
can be backported to stable tree.

I will fold patch2 and patch3 into one patch in v2.

Thanks for your review.
