This looks like a good change, but it raises the question of why we
did it this odd way to begin with?

Is it just because O_EXCL without O_CREAT is kind of odd, and only has
meaning for block devices?

Or is it just that before we used fiel pointers for block devices, the
old model made more sense?

Anyway, I like it, it just makes me go "why didn't we do it that way
