{sigh}

This is exactly what I did _NOT_ want to ever see happen when I did the
"let's announce the LTS kernels ahead of time" :(

I think I have to go back to the "announce them after the fact", as
pushing crap in before it is really ready is not acceptable.

I'd rather take "much more difficult to backport" issue than this "cram
it in now as we have a deadline to make".

We've been down this path before, and it was not good, there's a reason
our every 2-3 month release cycle works, and it is not because we take
stuff before it really is ready.

thanks,

greg k-h
