Update.

2000-07-26  Andreas Jaeger  <aj@suse.de>

	* rt/tst-aio.c: Add tests for aio_fsync and aio_cancel.
	(do_wait): Test requests with aio_return.
	(do_test): Change callers of do_wait.

2000-07-27  Ulrich Drepper  <drepper@redhat.com>

	* rt/aio_misc.c (__aio_remove_request): New function.  Handle removing
	from request list.  Don't do the list handling here, call
	__aio_remove_request.
	* rt/aio_misc.h: Add prototype for __aio_remove_request.
	* rt/aio_cancel.c: Don't assume __aio_find_req_fd succeeds since the
	request might already be processed.  Don't do the list handling
	here, call __aio_remove_request.

	* rt/aio_misc.c: Don't depend on aio_reqprio field for LIO_SYNC and
	LIO_DSYNC.

	* rt/aio_misc.c: Add comment explaining why writer memory barriers
	are missing.
