automatic IRQ affinity for virtio V2
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 V1:
- dropped the patches already merged for 4.10-rc
- new patch to
