I don't think this reply has anything to do with the sentiments expressed
by Geert above.  My interpretation of his comments is just that it is a
pity noone noticed the problem while it was only in linux-next and
reported it widely (like on linux-arch) so something could have been done
before it all Linus' tree.  There was no suggestion of slowing the pace
of development.
