From 6b9c2e671c08bd80606d9da81aee00bb03c44f90 Mon Sep 17 00:00:00 2001
From: Ulrich Drepper <drepper@redhat.com>
Date: Sat, 11 Apr 1998 20:19:13 +0000
Subject: Update.

	* rt/tst-aio.c: Add test for aio_read and lio_listio.

	* rt/lio_listio.c: Correct total counter handling.

	* rt/aio_misc.c (handle_fildes_io): Correctly dequeue elements
	from request queue.

	* test-skeleton.c (main): Make stdout unbuffered.  Improve message
	of signal on exit even more.
