Subject: Include count of pagecache pages in show_mem() output
X-Git-Tag: v2.6.25-rc1~927
X-Git-Url: http://bbs.cooldavid.org/git/?a=commitdiff_plain;h=e6f3602d2c58815775b2a293cec6650622236169;p=net-next-2.6.git

Include count of pagecache pages in show_mem() output

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.
