    Subject[PATCH 00/10] ksm resend
    Date
    Hey,

    First for who that is not familier with what is ksm please take a look at:
    http://lkml.org/lkml/2009/4/19/210

    About this send:

    After modifications by Hugh Dickins to make the ksm code fit more to the
    internal strctures / interfaces of the kernel, I am resending the whole seires
    again.

    The biggest change from previous version that was sent is: the moving into
    madvise interface for registering the application memory to be scan.
    Now when application want its memory to be merged with another applications
    what it do is to call to madvise() with the MADV_MERGEABLE flag set.

    In addition to changes to the interfaces of ksm,. there was a major code
    clean / optimizations made by Hugh.

    There is more work to be taken in the area of documentions, as well as some
    questions regerding to how ksm should handle the way it break the SharedPages
    when it need to do so, but the code seems to be ready to be in the MM tree
    right now to get more testing and reviews from other developers.

    The code still need to get Andrea Arcangeli acks.
    (he was busy and will ack it later).

    Thanks.
