Update.
2003-03-03 Martin Schwidefsky <schwidefsky@de.ibm.com> * atomic.h (atomic_exchange_and_add): Return newval, not oldval. * sysdeps/pthread/pthread_cond_timedwait.c (__pthread_cond_timedwait): Fix handling of cancellation and failing pthread_mutex_unlock call. * sysdeps/pthread/pthread_cond_wait.c (__condvar_cleanup): Likewise. (__pthread_cond_wait): Likewise. * sysdeps/pthread/pthread_rwlock_timedrdlock.c (pthread_rwlock_timedrdlock): Fix clobber of result variable by lll_futex_timed_wait call. * sysdeps/pthread/pthread_rwlock_timedwrlock.c (pthread_rwlock_timedwrlock): Likewise. * sysdeps/unix/sysv/linux/s390/libc-lowlevellock.c (___lll_lock): Don't define lll_unlock_wake_cb and ___lll_timedwait_tid in libc.so. * sysdeps/unix/sysv/linux/s390/lowlevellock.c: Remove XXX comments. * sysdeps/unix/sysv/linux/s390/sem_post.c (__new_sem_post): Fix check of lll_futex_wake return value.
