2006-01-04  Ulrich Drepper  <drepper@redhat.com>

	* sysdeps/pthread/aio_misc.h (struct waitlist): Add result member.
	* sysdeps/pthread/aio_notify.c (__aio_notify): For synchronous waiters,
	failed I/O, and a result pointer, set value to -1.
	* sysdeps/pthread/aio_suspend.c: Initialize result pointer to NULL.
	* sysdeps/pthread/lio_listio.c: For LIO_WAIT, point result pointer in
	wait list to local variable result.  If nonzero afterwards, set errno
	to EIO.  For LIO_NOWAIT set result to NULL.
	* rt/Makefile (tests): Add tst-aio8.
	* rt/tst-aio8.c: New file.
