That sounds very right aside from the global reserve. A given subsystem may exist in multiple instances and serve sub partitions of the system. F.e. there may be a network card on node 5 and a job running on nodes 3-7 and another netwwork card on node 15 with the corresponding nodes 13-17 doing I/O through it. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
