    Hi,

    today I released a new version of my VM patch for 2.4.0-test.

    This patch should mostly fix streaming IO performance, due
    to the following two features:
    - drop_behind(), when we do a readahead, move the pages
      'behind' us to the inactive list .. this way we can do
      streaming IO without putting pressure on the working set
    - deactivate pages in generic_file_write(), this does
      basically the same ... by moving the pages we write to
      to the inactive_dirty list, a big download, etc.. doesn't
      impact the working set of the system

    I'm particularly interested in the impact of streaming IO on
    the performance of the rest of the system with this patch, but
    of course also in the performance of the streaming IO itself.

    The patch is available from:
