* Fix missing wake-ups in pthread_rwlock_rdlock.Torvald Riegel2015-06-041-0/+183
This adds wake-ups that would be missing if assuming that for a non-writer-preferring rwlock, if one thread has acquired a rdlock and does not release it, another thread will eventually acquire a rdlock too despite concurrent write lock acquisition attempts. BZ 14958 is about supporting this assumption. Strictly speaking, this isn't a valid test case, but nonetheless worth supporting (see comment 7 of BZ 14958).
