    A new ->direct_IO2 hook would be an addition, so you really want to
    simply add another feature flag.

    Since the 2.5 direct_IO API is already different from current 2.4, I
    would also suggestion considering KERNEL24_HAS_O_DIRECT2 as the name, to
    specify the feature is specific to 2.4.
