    Just a hint for the future: when you're sending multiple versions of
    a patchset, it would be really helpful to have changelog in the 0/n
    message so that the reviewer can know what happened in each version.

    Rediff changes against -rc4

    Small cleanups, integrate comments.


    Otherwise, we have to go look at the older patches and compare what
