Re: [PATCH 1/1] vhost: support VIRTIO_F_RING_RESET for vhost-user

This patch will be updated in the future. We'll fix some issues based on some review comments from QEMU community. We intend to add a new vhost protocol message for virtqueue reset. Please let me know any questions or suggestions you might have. Thanks 在 2022/7/19 15:26, Kangjie Xu 写道:
