3.2 as well.

I don't know about easy, but if you have 'stable' as a remote then
this works:

$ git branch -r | sed 's/^ *stable\/linux-\([0-9.]*\)\.y/\1/; t; d' | while read version; do git rev-list --grep=080399aaaf3531f5b8761ec0ac30ff98891e8686 v$version..stable/linux-$version.y | grep -q . && echo $version; done
3.0
3.2
3.3

(Maybe I'll wrap that up in a script.)
 
Ben.
