Let's say I am an app which requires O_DIRECT, and which does not want to work with non-O_DIRECT. What would I do to ensure O_DIRECT? Could you please check what other file-systems which do not support O_DIRECT do in this case? Do they also fall-back to normal IO instead of explicitly failing? If yes, we can do what is considered to be the "standard" behavior.
