Subject: [PATCH 0/2] Reduce the amount of time spent in watermark-related functions
Date: Wed, 27 Oct 2010 09:47:34 +0100 [thread overview]
Message-ID: <1288169256-7174-1-git-send-email-mel@csn.ul.ie> (raw)
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
