I have a customer that would like the client to use DATA_SYNC instead of
FILE_SYNC when writing a file with O_DSYNC. It looks like the client will
only use FILE_SYNC since:

I've been unable to dig up any other discussion on this, so I think it
has just been an overlooked point until now. I'm only starting to
figure out what would need to change for this, and I thought that while
I do that I'd ask the list if anyone thinks that serious implementation
issues might emerge if this were attempted.
