Did this really have to go to so many people? akpm probably doesn't
need to know of this directly, Russell reads linux-arm-kernel so isn't
really a necessary CC: in this and you missed out the linux-usb list.

It's better than too few! Bugfixes are important (most important?)
and our lossage rate on patches is scary high.
In particular, please don't chase people's bugfixes off linux-kernel,
because then I won't see them. I'd guess that somewhere between a
quarter and a half of the bugfixes which I scoop off the list would
otherwise not have been applied.
Spread the wealth!
