The following two patches are in response to a bug report by Shaohua Li where the amount of time spent in zone_nr_free_pages() is unacceptable for large machines. All the background is in the first patches leader. The second patch replaces two setter functions with one function that takes a callback function as a parameter.
Mel Gorman (2): mm: page allocator: Adjust the per-cpu counter threshold when memory is low mm: vmstat: Use a single setter function and callback for adjusting percpu thresholds
