    Great thought, but it won't work unless you actually read them all, which I
    hope is what you're proposing.

    I'm a little skeptical about the chance of fitting an 11-parameter function
    call into a generic kernel plug-in framework. Are those the exact same 11
    parameters that God intended?

    While it would be great to share a single dlm between gfs and ocfs2 - maybe
    Lustre too - my crystal ball says that that laudable goal is unlikely to be
    achieved in the near future, whereas there isn't much choice but to sort out
    a common membership framework right now.

    As far as I can see, only cluster membership wants or needs a common
    framework. And I'm not sure that any of that even needs to be in-kernel.

    Regards,

    Daniel
