    Basically I was curious whether we can do more better with your directed
    yield discussions in https://lkml.org/lkml/2010/8/2/106 .

    I felt we can get little more improvement with doing directed yield to
    lock-holder in case of LHP than sleeping. But I may be wrong.

    So wanted to get the feedback, on whether I am thinking in right
    direction.
