* pthreadP.h (PTHREAD_ROBUST_MUTEX_PSHARED): Define.
* pthread_mutex_lock.c: Use it instead of PTHREAD_MUTEX_PSHARED when dealing with robust mutexes. * pthread_mutex_timedlock.c: Likewise. * pthread_mutex_trylock.c: Likewise. * pthread_mutex_unlock.c: Likewise. * sysdeps/unix/sysv/linux/pthread_mutex_cond_lock.c: Likewise. 2007-08-06 Jakub Jelinek <jakub@redhat.com> * pthreadP.h (PTHREAD_MUTEX_PSHARED_BIT): Define. (PTHREAD_MUTEX_TYPE): Mask __kind with 127. (PTHREAD_MUTEX_PSHARED): Define. * pthread_mutex_init.c (__pthread_mutex_init): Set PTHREAD_MUTEX_PSHARED_BIT for pshared or robust mutexes. * pthread_mutex_lock.c (LLL_MUTEX_LOCK): Take mutex as argument instead of its __data.__lock field, pass PTHREAD_MUTEX_PSHARED as second argument to lll_lock. (LLL_MUTEX_TRYLOCK): Take mutex as argument instead of its __data.__lock field. (LLL_ROBUST_MUTEX_LOCK): Take mutex as argument instead of its __data.__lock field, pass PTHREAD_MUTEX_PSHARED as second argument to lll_robust_lock. (__pthread_mutex_lock): Update LLL_MUTEX_LOCK, LLL_MUTEX_TRYLOCK, LLL_ROBUST_MUTEX_LOCK users, use PTHREAD_MUTEX_TYPE (mutex) instead of mutex->__data.__kind directly, pass PTHREAD_MUTEX_PSHARED (mutex) to lll_unlock and lll_futex_wait. * pthread_mutex_trylock.c (__pthread_mutex_trylock): Use PTHREAD_MUTEX_TYPE (mutex) instead of mutex->__data.__kind directly, pass PTHREAD_MUTEX_PSHARED (mutex) to lll_unlock.

Use PTHREAD_MUTEX_TYPE (mutex) instead of mutex->__data.__kind directly. * pthread_mutex_timedlock.c (pthread_mutex_timedlock): Pass PTHREAD_MUTEX_PSHARED (mutex) to lll_timedlock, lll_robust_timedlock, lll_unlock and lll_futex_timed_wait.
