commit ab8473b63982c814cdf509b8061fe0152cf3fd39

Fix PI mutex check in pthread_cond_broadcast and pthread_cond_signal
|
||||
|
||||
The check had a typo - it checked for PTHREAD_MUTEX_ROBUST instead of
|
||||
PTHREAD_MUTEX_NORMAL_ROBUST_NP. It has now been replaced by the
|
||||
already existing convenience macro USE_REQUEUE_PI.
