Update.
2003-06-22 Ulrich Drepper <drepper@redhat.com> * pthreadP.h (__pthread_mutex_init_internal): Mark hidden. (__pthread_mutex_lock_internal): Likewise. (__pthread_mutex_unlock_internal): Likewise. (__pthread_mutex_unlock_usercnt): Declare. * pthread_mutex_destroy.c: Always fail if used in any way. * pthread_mutex_init.c: Update comment. * pthread_mutex_lock.c: If NO_INCR is not defined adjust __nusers. * pthread_mutex_timedlock.c: Adjust __nusers. * pthread_mutex_trylock.c: Adjust __nusers. * pthread_mutex_unlock.c: Old code is in __pthread_mutex_unlock_usercnt and public interfaces are wrapper with pass additional parameter. __pthread_mutex_unlock_usercnt does not adjust __nusers if second parameter zero. * tst-mutex8.c: New file. * Makefile (tests): Add tst-mutex8. * sysdeps/pthread/pthread_cond_timedwait.c: Call __pthread_mutex_unlock_usercnt. * sysdeps/pthread/pthread_cond_wait.c: Likewise. * sysdeps/unix/sysv/linux/i386/i486/pthread_cond_timedwait.S: Likewise. * sysdeps/unix/sysv/linux/i386/i486/pthread_cond_wait.S: Likewise. * sysdeps/unix/sysv/linux/x86_64/pthread_cond_timedwait.S: Likewise. * sysdeps/unix/sysv/linux/x86_64/pthread_cond_wait.S: Likewise. * sysdeps/unix/sysv/linux/pthread_mutex_cond_lock.c: Define NO_INCR. * sysdeps/unix/sysv/linux/i386/bits/pthreadtypes.h (pthread_mutex_t): Add __nusers. * sysdeps/unix/sysv/linux/ia64/bits/pthreadtypes.h: Likewise. * sysdeps/unix/sysv/linux/powerpc/bits/pthreadtypes.h: Likewise. * sysdeps/unix/sysv/linux/s390/bits/pthreadtypes.h: Likewise. * sysdeps/unix/sysv/linux/sh/bits/pthreadtypes.h: Likewise. * sysdeps/unix/sysv/linux/x86_64/bits/pthreadtypes.h: Likewise. * pthread_mutex_lock.c: Don't store THREAD_ID in __owner, use TID. * pthread_mutex_timedlock.c: Likewise. * pthread_mutex_trylock.c: Adjust __nusers. * pthread_mutex_unlock.c: Compare with TID not THREAD_ID. * tst-mutex9.c: New file. * Makefile (tests): Add tst-mutex9. * sysdeps/i386/tls.h: Remove THREAD_ID definition. * sysdeps/ia64/tls.h: Likewise. * sysdeps/powerpc/tls.h: Likewise. * sysdeps/s390/tls.h: Likewise. * sysdeps/sh/tls.h: Likewise. * sysdeps/x86_64/tls.h: Likewise. * sysdeps/unix/sysv/linux/i386/bits/pthreadtypes.h (pthread_mutex_t): Change type of __owner. * sysdeps/unix/sysv/linux/ia64/bits/pthreadtypes.h: Likewise. * sysdeps/unix/sysv/linux/powerpc/bits/pthreadtypes.h: Likewise. * sysdeps/unix/sysv/linux/s390/bits/pthreadtypes.h: Likewise. * sysdeps/unix/sysv/linux/sh/bits/pthreadtypes.h: Likewise. * sysdeps/unix/sysv/linux/x86_64/bits/pthreadtypes.h: Likewise.
