    Angry How to enable clock_pro option in linux?

    I read paper "LIRS:An Efficient Low Inter-reference Recency SetReplacement Policy. by Song Jiang" and "Clock-Pro by Rik Van Riel"
    And from their website, I know that Clock_pro(the approximate version of LIRS) has been supported in linux kernel 2.6.9. Now my question is how to enable the clock_pro option in linux. As a result, the page replacement algorithm is clock_pro but not LRU.

    Please replay.....Thanks

    I can be found either 40 miles west of Chicago, in Chicago, or in a galaxy far, far away.
    Well, it isn't accessible in the kernel configuration tools, so my guess is that this is hard-coded in the kernel. I would suggest you try to communicate with the kernel maintainers at The Linux Kernel Archives to find out which components implement this.
    Sometimes, real fast is almost as good as real time.
