[PATCH 0/6] refactor RDMA live migration based on rsocket API

From: Jialin Wang Hi, This patch series attempts to refactor RDMA live migration by introducing a new QIOChannelRDMA class based on the rsocket API. The /usr/include/rdma/rsocket.h provides a higher level rsocket API that is a 1-1 match of the normal kernel 'sockets' API, which hides the detail
