From b1e7a8fd854d2f895730e82137400012b509650e Mon Sep 17 00:00:00 2001 From: Christoph Lameter Date: Fri, 30 Jun 2006 01:55:39 -0700 Subject: [PATCH] zoned vm counters: conversion of nr_dirty to per zone counter This makes nr_dirty a per zone counter. Looping over all processors is avoided during writeback state determination. The counter aggregation for nr_dirty had to be undone in the NFS layer since we summed up the page counts from multiple zones. Someone more familiar with NFS should probably review what I have done.
