Subject: [PATCH 0/8] remove memory info from list before freeing it
Date: Fri, 20 Jul 2012 15:08:31 +0800 [thread overview]
Message-ID: <500903EF.70200@cn.fujitsu.com> (raw)
In-Reply-To: <5009038A.4090001@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.
