    I don't know what this means, really.

    AIO eventfd support is a relatively recently added enhancement to AIO,
    is it not? Applications which continue to use the pre-May07 AIO
    features will continue to work as before (they darn well better). So
    for such applications, AIO=y/EVENTFD=n kernels are usable and useful,
    and eliminating this option is a loss?

    Either way, I believe that this change should be unbundled from the
    unrelated KVM one so we can handle it separately.
