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

sparse produces these warnings: drivers/gpu/drm/virtio/virtgpu_fb.c:340:27: warning: incorrect type in assignment (different address spaces) drivers/gpu/drm/virtio/virtgpu_fb.c:340:27: expected char [noderef] <asn:2>*screen_base drivers/gpu/drm/virtio/virtgpu_fb.c:340:27: got void *vmap This is because the expected type is void __iomem *, while virtio gpu object is void *vmap. We could just cast the warning away but I'm not sure this is not a symptom of an actual problem. For example, mi...
