Subject: [PATCH 3/8] remove memory info from list before freeing it
Date: Tue, 26 Jun 2012 17:20:15 +0800 [thread overview]
Message-ID: <4FE97ECF.2000903@cn.fujitsu.com> (raw)
In-Reply-To: <4FE97DD5.6030205@cn.fujitsu.com>
We free info, but we forget to remove it from the list. It will cause
unexpected problem when we access the list next time.
