After careful consideration and testing, I don't think getting the uring_lock is possible here, for the following reasons: Due to lock competition, ctx->uring_lock and sq->lock are usually not available here. The best proof is that the values of SqThread and SqThreadCpu always output -1. In this case, it is impossible to obtain the required work_time and total_time values. In fact, it should be feasible to obtain work_time and total_time by judging that ctx->sq_data is not NULL, because if the sq thread exits, the action of reading data will also stop, and the possibility of a null pointer reference is very low.
