I have often read this message and wondered why no one has implemented it yet. We would love to have such clean features instead of O_DIRECT. At this very moment it's a bit hard for us to do this(given a prerequisites learning curve amongst other factors.) We may at some point do it and I'd love to contribute. What _are_ the issues with it, and is there a technical reason it hasn't been implemented yet by anybody?
Further, is O_DIRECT to raw partition also unclean?
Thanks.
