Subject: [Patch] Include count of pagecache pages in show_mem() output.
Date: Mon, 07 Jan 2008 14:12:36 -0500 [thread overview]
Message-ID: <478279A4.3030903@redhat.com> (raw)
[-- Attachment #1: Type: text/plain, Size: 306 bytes --]
The show_mem() output does not include the total number of
pagecache pages. This would be helpful when analyzing the
debug information in the /var/log/messages file after OOM kills
occur.
This patch includes the total pagecache pages in that output:
