The numbers are for the original driver vs the new driver. For
purposes of calculating
them, I had sysctls in the code (removed for submission) in the
original and the new
driver at each of the locations given above (a simple
atomic64_inc(&kk_arfs_add), etc).

I will re-send the patch after adding this table (and Simon's feedback).

I have a large set of scripts that measure each of these parameters.
If you wish, I can
send you the set of scripts separately.
