We should not need multiple submission queues for IRQ steering. We just need to build the cpu to vector reverse map that blk_mq_pci_map_queues builds.

In the meantime you can just opencode that loop. -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
