That sounds like good testing \o/ If you are happy with i2ctransfer,
then please consider adding Tested-by tags to the i2ctransfer patches,
so Jean gets a more cosy feeling to include them to i2ctools.

I am happy for indications like "please consider adding this line for
stable: ...", but not CC stable yourself. These patches need changes,
so they are noise for the stable lists. The ones I ultimately apply are
the proper ones.

That being said, I'll mark all your patches "changes reqeuested" since you
need to resend based on current review from James (thanks a lot!). Even
if some patches are good and got acked, but it is easier for me to mark
them all the same :)
