The message is to warn people of possible behavior changes.  For
blk-throttle, the behaviors are settled now.  Whetner sane_behavior or
not, the hierarchy behaviors aren't gonna change anymore.  The
hindsight is 20/20 and it would probably have been better if we had
done the same for cfq but I was thinking that we could probably do
away with interface versioning at the time.  Ah well... it isn't
optimal but that's what we ended up with.

Thanks.
