Commit 653055b9acd4 ("vhost-vdpa: support get/set backend features")
introduces two malfunction backend features ioctls:

1) the ioctls was blindly added to vring ioctl instead of vdpa device
    ioctl
2) vhost_set_backend_features() was called when dev mutex has already
    been held which will lead a deadlock

I assume this patch requires some patch in qemu as well. Do you have
such patch?

It's this series: [PATCH 0/3] Vhost-vDPA: batch IOTLB updating.
