Revert "oom: oom_kill_process: fix the child_points logic"
This reverts the parent commit. I hate doing that, but it's generating some discussion ("half of it is right"), and since I am planning on doing the 2.6.38 release later today we can punt it to stable if required. Let's not rock the boat right now. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
