[I] contention profiler是否支持pthread_wrlock (brpc)
chenBright opened a new issue, #2133:
URL: https://github.com/apache/brpc/issues/2133
https://github.com/BrianGladman/pthreads/blob/master/pthread_rwlock_wrlock.c
https://android.googlesource.com/platform/external/pthreads/+/216eb8153b2455d1e15f8fbf84d4413ddcc40adc/pthread_rwlock_wrlock.c
看了两个实现，pthread_wrlock是用pthread_mutex_lock实现的，所以contention profiler应该也支持pthread_wrlock的吧？

应该是不支持的，这个和符号查找顺序有关，对于pthread_mutex_lock的hook没法影响到到glibc.so内部调用。
