Applied, but like Ben said perhaps you want to remember the last cpu you got the sched_clock() measurement from and abort the ll poll if it changes on you instead of using a comparison between two cpus. But then again, since preemption is enabled, the cpu could change back and forth during the sched_clock() call, so you wouldn't be able to reliably detect this anyways. In the grand scheme of things all of this probably doesn't matter at all. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
