    Some guy named Andrew used to run a kernel with 'return 0' at the top
    of fsync and fdatasync: http://lkml.org/lkml/2007/4/27/88

    It's that the latency penalty of apps using *sync() on common hardware
    sucks. That's all, and finding a way to fix that would make this
    entire thread go away, I think.
