    It seems odd that we require implementing ->atomic_create even if we
    don't actually do an atomic create but just want to look at the flags.

    In fact I wonder if we really need to bother with having ->atomic_create
    and ->create, or if we should have one method (kinda contra my previous
    stance that ->atomic_open and ->atomic_create should be one).

    This method then could or could not return a file pointer, but it would
    always be the entry point for creates.
