[Impact]
* pthread_rwlock_trywrlock and pthread_rwlock_tryrdlock before glibc 2.30 could hang: https://sourceware.org/bugzilla/show_bug.cgi?id=23844#c14
* We are especially able to reproduce the problem with BIND 9.16.x when --with-pthread-rwlock configure option enabled
* But the impact is not limited to BIND 9.16, but any multithreaded application using phtread rwlocks
[Test Case]
* There's three test cases included in the upstream bugzilla
[Regression Potential]
* I don't believe there's a chance for regressions here
