Hi Ingo, Thomas, this one-liner fixes a bug in balance_rt_tasks() which sometimes manifests by having a lower prio task being scheduled while a higher prio task is sitting waiting on another runqueue. This is pretty hard to reproduce on low cpu count machines, for example, I had to have sched_football run in a loop for ~38h before it failed on a dual HT Xeon box.
really nice catch! Applied. Ingo
