    Subject[-mm PATCH 0/7] Memory controller introduction
    Resending with the patch numbering fixed and linux-mm copied

    This patchset implements another version of the memory controller. These
    patches have been through a big churn, the first set of patches were posted
    last year and earlier this year at

    Ever since, the RSS controller has been through four revisions, the latest
    one being

    This patchset draws from the patches listed above and from some of the
    contents of the patches posted by Vaidyanathan for page cache control.

    Pavel, Vaidy could you look at the patches and add your signed off by
    where relevant?

    At OLS, the resource management BOF, it was discussed that we need to manage
    RSS and unmapped page cache together. This patchset is a step towards that


    1. Add memory controller water mark support. Reclaim on high water mark
    2. Add support for shrinking on limit change
    3. Add per zone per container LRU lists
    4. Make page_referenced() container aware
    5. Figure out a better CLUI for the controller

    In case you have been using/testing the RSS controller, you'll find that
    this controller works slower than the RSS controller. The reason being
    that both swap cache and page cache is accounted for, so pages do go
    out to swap upon reclaim (they cannot live in the swap cache).

    I've test compiled the framework without the controller enabled, tested
    the code on UML and minimally on a power box.

    Any test output, feedback, comments, suggestions are welcome!



    Warm Regards,
