1999-07-09  Ulrich Drepper  <drepper@cygnus.com>

	* manager.c (pthread_handle_create): Free mmap region after stack
	if clone failed.  Patch by Kaz Kylheku <kaz@ashi.FootPrints.net>.

1999-05-23  Andreas Jaeger  <aj@arthur.rhein-neckar.de>

	* man/pthread_cond_init.man: Correct example.
	Reported by Tomas Berndtsson <tomas@nocrew.org>.

	* linuxthreads.texi (Condition Variables): Likewise.

1999-05-18  Jakub Jelinek  <jj@ultra.linux.cz>

	* sysdeps/sparc/sparc64/pt-machine.h (__compare_and_swap): Use
	casx not cas, also successful casx returns the old value in rd
	and not the new value.

1999-05-16  Xavier Leroy  <Xavier.Leroy@inria.fr>

	* manager.c: If pthread_create() is given a NULL attribute
	and the thread manager runs with a realtime policy, set the
	scheduling policy of the newly created thread back to SCHED_OTHER.
	* manager.c: If the PTHREAD_INHERIT_SCHED attribute is given,
	initialize the schedpolicy field of new_thread->p_start_args
	to that of the calling thread.

1999-04-29  Ulrich Drepper  <drepper@cygnus.com>

	* sysdeps/sparc/sparc64/pt-machine.h (__compare_and_swap): cas
	instruction does not allow memory element to use offset.

1999-04-28  Ulrich Drepper  <drepper@cygnus.com>

	* manager.c (pthread_allocate_stack): Optimize initialization of new
	thread descriptor.

	* sysdeps/pthread/bits/libc-lock.h (__libc_lock_define_initialized):
	Don't use initializer since it is all zeroes.
	(__libc_once_define): Likewise.
