    The documentation I could find suggests that this may lead to a
    security weakness (old data in blocks of a file that was grown just
    before the crash leaks to a different user). XFS overwrites that data
    with zeros upon reboot, which tends to irritate users when it happens.

    From this point of view, data=ordered doesn't seem too bad.
