I flushed that one down the toilet because while lowest possible service latency always sounds super sexy, it has down sides. Rabid migration does not do great things for throughput, for instance, that patch slagged the throughput gain for tbench that put DELAY_DEQUEUE equipped kernels back on par with pre-EEVDF kernels. Not a keeper. -Mike
