OK, I grabbed this.
I made a number of changelog changes:
- Rewrote it as From: Andrea (correct?)
- Replaced your acked-by with signed-off-by, as you were on the
delivery path
- Hunted down Arthur's email address and added his reported-by and
tested-by.
- Added cc:stable, as it's a bit late for 2.6.38. The intention
being that we put this into 2.6.38.1 after it has cooked in 2.6.39-rcX
for a while. OK?
