From 9a865ffa34b6117a5e0b67640a084d8c2e198c93 Mon Sep 17 00:00:00 2001 From: Christoph Lameter Date: Fri, 30 Jun 2006 01:55:38 -0700 Subject: [PATCH] zoned vm counters: conversion of nr_slab to per zone counter - Allows reclaim to access counter without looping over processor counts. - Allows accurate statistics on how many pages are used in a zone by the slab. This may become useful to balance slab allocations over various zones.
