LoopbackDevice的实现分为四层：

解决actix-web与epoll的适配

详见 [Bug] 是否考虑资源限制对 epoll管理socket存在问题 - DragonOS开源社区

解决在运行 test-backlog 程序时，行为与预期不符的问题。

问题复现与跟踪

使用 strace 跟踪 epoll_ctl 和 epoll_wait 系统调用。复现 test-backlog 程序的两个进程共享 epoll 实例管理 socket 的问题。

原因分析

分析 epoll_ctl 在 EPOLL_CTL_ADD 操作缺失的原因。调查 cgroup 或mmap map_fixed等资源限制有关功能缺失对 epoll 和 socket 管理的影响。
