Original GitHub issue: https://github.com/deepseek-ai/3FS/issues/273

应用进程调用hf3fs_iorcreate4创建IoRing实例，然后调用hf3fs_prep_io把sqe添加到IoRing实例中，最后调用hf3fs_submit_ios发送信号量通知FuseClients::watch线程处理IoRing中的sqe。但是FuseClients::watch函数查找IoRing实例时，只是通过比较优先级来取IoRing实例。相关代码如下：
... if (ior && ior->priority == prio) { auto jobs = ior->jobsToProc(config->max_jobs_per_ioring()); for (auto &&job : jobs) { gotJobs = true; iojqs[prio]->enqueue(std::move(job)); } } ....
想请问下，hf3fs_prep_io时使用的IoRing实例是怎么和FuseClients::watch中使用的IoRing实例一一对应的？
