It must be, maybe block just got merged first? It's just sched/core in a topic branch, to satisfy a dependency. But as mentioned in the previous email, I just need sched/smp to satisfy that dependency. So I've rebased that small topic branch with that pulled in instead. Won't solve the sched/core vs rcu tree conflict, but at least it's out of my hands now :-) -- Jens Axboe
