Linus,
Please pull the latest perf-urgent-for-linus git tree from:
git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip.git perf-urgent-for-linus
I kept this one really simple, because AFAICS this is the first ever
3.0 pull request sent to you on lkml, and i do not want to go down in
history as the idiot who sent the first broken tree to you in this
new and exciting 3.0 kernel age! ;-)
Thanks,
Ingo
