See http://www.infradead.org/rpr.html Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org 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 correctly - add a few Reviewed-by: tags for Jason Changes since V1: - dropped the patches already merged for 4.10-rc - new patch to remove struct virtio_pci_vq_info - improve probe error handling by unwinding step by step - new patch to convert virtio-scsi
