+ * tst-rwlock6.c: More pthread_rwlock_timedwrlock and
+ pthread_rwlock_timedrdlock tests.
+ * tst-rwlock7.c: More pthread_rwlock_timedwrlock tests.
+ * sysdeps/unix/sysv/linux/i386/i486/pthread_rwlock_timedrdlock.S:
+ Check for invalid tv_nsec field.
+ * sysdeps/unix/sysv/linux/i386/i486/pthread_rwlock_timedwrlock.S:
+ Likewise.
+
+ * pthread_mutex_trylock.c (__pthread_mutex_trylock): Protect
+ recursive mutex of overflow.
+
+ * tst-attr1.c (do_test): Add test for pthread_mutexattr_setpshared.
+
* libc-cancellation.c (__libc_enable_asynccancel): Rwrite to avoid
going into an endless loop.
* Makefile (tests): Add tst-cancel9.
