    It relies on infrastructure which is not present in Linus's kernel. We
    should only be interested in fixing mainline 2.6.x.

    Furthermore I'd like to see the direct-vs-buffered locking fixes fully
    implemented against Linus's tree, not -mm. They're almost there, but are
    not quite complete. Running off and making it dependent on the retry
    infrastructure is not really helpful.
