Xie Yongji 5ad204bf2a vhost-user: Support transferring inflight buffer between qemu and backend ... This patch introduces two new messages VHOST_USER_GET_INFLIGHT_FD and VHOST_USER_SET_INFLIGHT_FD to support transferring a shared buffer between qemu and backend. Firstly, qemu uses VHOST_USER_GET_INFLIGHT_FD to get the shared buffer from backend. Then qemu should send it back through VHOST_USER_SET_INFLIGHT_FD each time we start vhost-user. This shared buffer is used to track inflight I/O by backend. Qemu should retrieve a new one when vm reset.
