Oh Gods. Let's *not* make this some "random filesystem choice" where
now semantics depends on what some filesystem decided to do, and
different filesystems have very subtly different semantics.

This all screams "please keep this in the VFS layer" so that we at
least have _one_ place where these kinds of decisions are made.

I suspect very very few people actually end up caring about any of the
STATX flags at all, of course. The fact that the DAX one was
apparently entirely the wrong bit argues that this isn't all that
important.
