    Yes. I posted it to lkml, and the virtualization list, on the 30th of April.
    I thought you had seen that.

    I don't mind you picking up the work, I have so many other things to do.
    But I did post a working version.

    It wasn't merged for 2.6.22 because it was so close to the merge window
    and so much other code was already in Andi queue.

    If need be I can dig it up again and repost.
