Subject: [PATCH] Document the new Anonymous field in smaps.
Date: Thu, 16 Sep 2010 11:34:59 +0530 [thread overview]
Message-ID: <201009161135.00129.knikanth@suse.de> (raw)
In-Reply-To: <20100916125147.CA08.A69D9226@jp.fujitsu.com>
Sorry, I missed to add documentation, when I sent the patch. This depends on
the patch titled, "[PATCH] Export amount of anonymous memory in a mapping via
smaps".
Thanks
Nikanth
