Subject: [PATCH 11/14] Conversion of nr_writeback to per zone counter
Subject: zoned vm counters: conversion of nr_writeback to per zone counter
Date: Wed, 21 Jun 2006 08:45:16 -0700 (PDT) [thread overview]
Message-ID: <20060621154516.18741.50905.sendpatchset@schroedinger.engr.sgi.com> (raw)
In-Reply-To: <20060621154419.18741.76233.sendpatchset@schroedinger.engr.sgi.com>
Conversion of nr_writeback to per zone counter.
This removes the last page_state counter from arch/i386/mm/pgtable.c
so we drop the page_state from there.
