I actually don't rebase from main-version to main-version (that doesn't
really work), but I'm using format-patch and git am. It's a bit more
strict when that's ok. I haven't looked in deep which changes in 3.15 do
conflict with the patch based on 3.14, but it't can't be that much.

Sure, but I already did that in the reply to your patch.

No, I'm just too often the object of their first steps and that's why I
won't post any patches on lkml anymore. It might be fun for them to do
reviews on patches from innocent people, but those victims usually don't
share their view. Maybe I will choose full disclosure or similiar I ever
will have an important patch poor Linux users should really have a need for.
