Subject: [PATCH 20/21] Conversion of nr_bounce to per zone counter
Subject: zoned vm counters: conversion of nr_bounce to per zone counter
Date: Mon, 12 Jun 2006 14:14:28 -0700 (PDT) [thread overview]
Message-ID: <20060612211428.20862.63424.sendpatchset@schroedinger.engr.sgi.com> (raw)
In-Reply-To: <20060612211244.20862.41106.sendpatchset@schroedinger.engr.sgi.com>
Conversion of nr_bounce to a per zone counter
nr_bounce is only used for proc output. So it could be left as an
event counter. However, the event counters are not accurate and nr_bounce is
categorizing types of pages in a zone. So we really need this to also be a
per zone counter.
