From edfbe2b0038723e5699ab22695ccd62b5542a5c1 Mon Sep 17 00:00:00 2001 From: KAMEZAWA Hiroyuki Date: Sun, 1 May 2005 08:58:37 -0700 Subject: [PATCH] count bounce buffer pages in vmstat This is a patch for counting the number of pages for bounce buffers. It's shown in /proc/vmstat. Currently, the number of bounce pages are not counted anywhere. So, if there are many bounce pages, it seems that there are leaked pages. And it's difficult for a user to imagine the usage of bounce pages. So, it's meaningful to show # of bouce pages.
