Well we have discussed this repeatedly and the upstream solution was to reduce the vm statistics thresholds. My contribution to the patch mentioned above was only the zone_page_state_snapshot function. The rest is from Mel. AFAICT The fixup to this was 88f5acf88ae6a9778f6d25d0d5d7ec2d57764a97 mm: page allocator: adjust the per-cpu counter threshold when memory is low _______________________________________________ stable mailing list [email protected] http://linux.kernel.org/mailman/listinfo/stable
