Description

We have had directio(3c) support for a very long time, but on Linux this s controlled via the O_DIRECT option flag to open(2). This difference causes porting overhead for applications developed on Linux. To eliminate this friction, we can add O_DIRECT support which is equivalent to directio(DIRECTIO_ON) as part of our open(2).
