So the way you could have picked it up is something like:
# pick up 533445c6e533 git fetch git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git sched/urgent git cherry-pick 533445c6e533
or pick up all pending scheduler fixes, amongst them 533445c6e533:
git pull git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git sched/urgent
Or to export just that single one as a patch:
git fetch git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git sched/urgent git log --pretty=email --stat -p -1 533445c6e533

Great, thanks for testing!
