Where do you see this as a problem? I can cook up a patch but will need some justification which I have a hard time to come up with ;)
I was learning about this stuff and wrote some hello world test and found that the behavior was inconsistent (and undocumented) when running it in different partitions. (first in /tmp --> tmpfs, then /var/tmp --> SSD ext4)
I see
I have not found a real world app that breaks, but wouldn't be surprised if some do. ;)
I can hardly imagine such an app ;) It sounds really strange that you would fail (in what ever way) just because you are not able to set a hint which is not guaranteed to be acted upon on. I do agree that EINVAL is just a terrible way to communicate that but this is how we do it for ages so the change needs a _really_ good usecase.
Thanks for the clarification.
