Subject: zoned vm counters: conversion of nr_bounce to per zone counter
From: Christoph Lameter <clameter@xxxxxxx>
Conversion of nr_bounce to a per zone counter
nr_bounce is only used for proc output. So it could be left as an
eventcounter. However, the eventcounters are not accurate and nr_bounce is
categorizing one type of page in a zone. So we really need this to also be a
per zone counter.
