I tested this patchset with stress-highalloc benchmark on Mel's mmtest and cannot find any regression in terms of success rate. And I find much reduced system time. Below is result of 3 runs. * Before time :: stress-highalloc 3276.26 user 740.52 system 1664.79 elapsed time :: stress-highalloc 3640.71 user 771.32 system 1633.83 elapsed time :: stress-highalloc 3691.64 user 775.44 system 1638.05 elapsed avg system: 1645 s * After time :: stress-highalloc 3225.51 user 732.40 system 1542.76 elapsed time :: stress-highalloc 3524.31 user 749.63 system 1512.88 elapsed time :: stress-highalloc 3610.55 user 757.20 system 1505.70 elapsed avg system: 1519 s That is 7% reduced system time. Thanks.
