Merge tag 'for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mst/vhost

Pull virtio updates from Michael Tsirkin:
 "virtio,vhost,vdpa: features, fixes, and cleanups:

   - reduction in interrupt rate in virtio

   - perf improvement for VDUSE

   - scalability for vhost-scsi

   - non power of 2 ring support for packed rings

   - better management for mlx5 vdpa

   - suspend for snet

   - VIRTIO_F_NOTIFICATION_DATA

   - shared backend with vdpa-sim-blk

   - user VA support in vdpa-sim

   - better struct packing for virtio

  and fixes, cleanups all over the place"
