target如何支持热升级过程中nvmf不断连

https://mp.weixin.qq.com/s/t6dXP1_Cx7YBT4bV7odqCA 一文中介绍liteio有提到： "Target 整体框架如下图所示，在热升级期间必须保持 nvmf 的网络连接不可中断，否则 host 侧会感知并去重连或者删除盘符，热升级采用旧的 target 程序 fork 新的 target 程序并加载新的二进制文件来实现，整个热升级过程中 IO 不可丢失，新旧进程的切换速度要快。基于热升级框架的简单性设计原则，热升期间下图中绿色的 TCP 或 RDMA 连接为必须保持的上下文，其他模块均无需保存上下文状态，网络连接的保持通过父子进程继承文件描述符的方式实现。" 我在liteio开源代码中没有找到这方面的实现，请问这个特性有进行开源吗
