Umm. The kernel developer _did_ do the job. The patch to the user land
side was available for that whole year. It just didn't get merged, and
then didn't get merged some more, and then got merged but only in a SVN
tree, not a release, and then finally when I did a bugzilla request to
fedora, they took the patch and put it in their distro.
Anyway, it's clearly not worth discussing this with you. I've tried. I
give up. Happily, I don't _need_ to convince you.
