Your stats concerning the personal contribution to stable seem at first look pretty screwed:
First of all it is not easy to find the one that forwarded a particular patch to stable.
Secondly most in all times this random person gets gets showed into the Cc: of the stable patch and thus is not distinguisable from usual Cc's that happen to be listed there.
A quick grep in the stable queue 2.6.32 releases showed 47 contributions of mine, but I'm 100% sure not to be the top contributor of it. But that forwarded patch number is certainly a lower bound.
Please explain how you generated the stats concerning the most active contributor. Thanks.
