Hi Bjorn,

This patch seems like independent of the other patch to split the AER
stats. Can you review and apply this one so that I don't have to keep
sending v4, v5 (where each version is basically same as v1) ... of
this patch with every iteration of the other patch?

I'll be working on Greg's and your comments on the other patch.

Thanks,

Rajat
