And I really do not think it is a good idea. For one it actually works against the stated intent of the FDP spec. Second extending the hints to per per-I/O in the io_uring patch is actively breaking the nice per-file I/O hint abstraction we have right now, and is really unsuitable when actually used on a file and not just a block device. And if you are only on a block device I think passthrough of some form is still the far better option, despite the problems with it mentioned by Keith.
