    Thus far our (my) approach has been to trickle the c/r support code
    into mainline as it is developed. Under the assumption that the end
    result will be acceptable and useful kernel code.

    I'm afraid that I'm losing confidence in that approach. We have this
    patchset, we have Stanislav's "IPC: checkpoint/restore in userspace
    enhancements" (which apparently needs to get more complex to support
    LSM context c/r). I simply *don't know* what additional patchsets are
    expected. And from what you told me it sounds like networking support
    is at a very early stage and I fear for what the end result of that
    will look like.

    So I don't feel that I can continue feeding these things into mainline
    until someone can convince me that we won't have a nasty mess (and/or
    an unsufficiently useful feature) at the end of the project.

    The traditional approach is to develop the feature out-of-tree until it
    is "finished". That's a lot more hackwork for you guys and it leads to
    a poorer feature - this approach inevitably has a lower level of review
    and inhibits code rework.

    An alternative is for me to buffer the patches in my tree until it is
    all sufficiently finished. That also is more work for your team, but
    it will produce better code, because of additional review and code
    rework resulting from that review.

    I don't know how many patches that would end up being (this is part of
    the problem!) nor how long they would be carried for.

    So. Please talk to me. How long is this all going to take, and what
    will the final result look like?
