Please refer to:


So this line is there since v5.

I took it an honor (and also with my thankfulness) to have added your
r-b line here. I assume what you meant before was: the patch content
is okay, but you would suggest to drop this patch in this series, and
merge this until we got a real implementations for the notifiers. IMHO
that does not mean "remove your r-b in this patch". If you meant to
remove this line (I think not?), please confirm and I can remove it.

I posted patch 3 just to make sure everything is coherent, and let
Paolo decide which way to choose (since I still think it's okay
actually... but again both are ok to me). Also it'll be easier for
Jason to track this down as well (so when Jason sees that Paolo
dropped patch 3, he'll naturally pick it up). If you still insist on
dropping this patch, I'll do it in v7.
