[PATCH 0/2] Reduce the amount of time spent in watermark-related functions

[Mel Gorman]

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
