From: Tomohiro Kusumi <tkusumi@xxxxxxxxxx>
This lets platforms without dio (e.g. OpenBSD) fail with an explicit
message, otherwise they fail without a clue about dio even with
--debug=all enabled.
The message assumes platforms with O_DIRECT do not call this function
(and in fact they don't so it's not really a problem).
