Hi Michael, this series contains a couple cleanups for the virtio_pci interrupt handling code, including a switch to the new pci_irq_alloc_vectors helper, and support for automatic affinity by the PCI layer if the consumers ask for it. It then converts over virtio_blk to use this functionality so that it's blk-mq queues are aligned to the MSI-X vector routing. I have a similar patch in the

Hi Michael, hi Jason, This patches applies a few cleanups to the virtio PCI interrupt handling code, and then converts the virtio PCI code to use the automatic MSI-X vectors spreading, as well as using the information in virtio-blk and virtio-scsi to automatically align the blk-mq queues to the MSI-X vectors. Changes since V2: - remove a redundant callback check - calculate ->msix_vectors
