Merge tag 'for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mst/vhost
Pull virtio updates from Michael Tsirkin: "Several new features here: - Virtio find vqs API has been reworked (required to fix the scalability issue we have with adminq, which I hope to merge later in the cycle) - vDPA driver for Marvell OCTEON - virtio fs performance improvement - mlx5 migration speedups Fixes, cleanups all over the place" * tag 'for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mst/vhost: (56 commits) virtio: rename virtio_find_vqs_info() to virtio_find_vqs() virtio: remove unused virtio_find_vqs() and virtio_find_vqs_ctx() helpers virtio: convert the rest virtio_find_vqs() users to virtio_find_vqs_info() virtio_balloon: convert to use virtio_find_vqs_info() virtiofs: convert to use virtio_find_vqs_info() scsi: virtio_scsi: convert to use virtio_find_vqs_info() virtio_net: convert to use virtio_find_vqs_info() virtio_crypto: convert to use virtio_find_vqs_info() virtio_console: convert to use virtio_find_vqs_info() virtio_blk: convert to use virtio_find_vqs_info() virtio: rename find_vqs_info() op to find_vqs() virtio: remove the original find_vqs() op virtio: call virtio_find_vqs_info() from virtio_find_single_vq() directly virtio: convert find_vqs() op implementations to find_vqs_info() virtio_pci: convert vp_*find_vqs() ops to find_vqs_info() virtio: introduce virtio_queue_info struct and find_vqs_info() config op virtio: make virtio_find_single_vq() call virtio_find_vqs() virtio: make virtio_find_vqs() call virtio_find_vqs_ctx() caif_virtio: use virtio_find_single_vq() for single virtqueue finding vdpa/mlx5: Don't enable non-active VQs in .set_vq_ready() ...
