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 2: - updated to mmotm-2010-03-09-19-15 - schedule a timeout for current if it was not selected for oom kill when it has returned VM_FAULT_OOM so memory can freed to prevent needlessly recalling the oom killer and looping. To apply, download the -mm tree from http://userweb.kernel.org/~akpm/mmotm/broken-out.tar.gz first.
