    Subject[patch -mm 0/9 v2] oom killer rewrite
    This patchset is a rewrite of the out of memory killer to address several
    issues that have been raised recently. The most notable change is a
    complete rewrite of the badness heuristic that determines which task is
    killed; the goal was to make it as simple and predictable as possible
    while still addressing issues that plague the VM.

    Changes from version 1:

    - updated to mmotm-2010-02-11-21-55

    - when iterating the tasklist for mempolicy-constrained oom conditions,
    the node of the cpu that a MPOL_F_LOCAL task is running on is now
    intersected with the page allocator's nodemask to determine whether it
    should be a candidate for oom kill.

    - added: [patch 4/9] oom: remove compulsory panic_on_oom mode

    - /proc/pid/oom_score_adj was added to prevent ABI breakage for
    applications using /proc/pid/oom_adj. /proc/pid/oom_adj may still be
    used with the old range but it is then scaled to oom_score_adj units
    for a rough linear approximation. There is no loss in functionality
    from the old interface.

    - added: [patch 6/9] oom: deprecate oom_adj tunable

    This patchset is based on mmotm-2010-02-11-21-55 because of the following

    [patch 5/9] oom: badness heuristic rewrite:

    [patch 7/9] oom: replace sysctls with quick mode:

    To apply to mainline, download 2.6.33-rc8 and apply


    from first.
