[PATCH net 0/4] Fix various issue of vhost
Hi:
This series tries to fix various issues of vhost:
- Patch 1 adds a missing write barrier between used idx updating and
logging.
- Patch 2-3 brings back the protection of device IOTLB through vq
mutex, this fixes possible use after free in device IOTLB entries.
- Patch 4 fixes the diry page logging when device IOTLB is
enabled. We should done through GPA instead of GIOVA, this was done

[RFC PATCH 00/24] Control VQ support in vDPA
Hi All:
This series tries to add the support for control virtqueue in vDPA.
Control virtqueue is used by networking device for accepting various
commands from the driver. It's a must to support multiqueue and other
configurations.
When used by vhost-vDPA bus driver for VM, the control virtqueue
should be shadowed via userspace VMM (Qemu) instead of being assigned
directly to Guest. This is
