this is a test project from issue: apache/brpc#2726
因为不想直接再编译一次brpc，以及它的相关依赖。这里我提供了一个mock_brpc_mutex.cpp
文件的内容基本是从：https://github.com/apache/brpc/blob/master/src/bthread/mutex.cpp 里拷贝出来的，为了方便说明，仅做了一些删减。
基本上只包含了pthread_mutex_trylock的相关代码。
dockerfile文件夹下，有我使用的测试环境的dockerfile。 在这个镜像下，可以直接在mock_brpc文件夹下执行
bash buid.sh之后会产出一个可执行文件main_exe
可以直接
gdb ./main_exe此时进程会卡住，control + c后可以通过bt命令查看栈，
即复现了issue中的栈结构
