Subject: [PATCH 3/7 v2] remove memory info from list before freeing it
Date: Wed, 11 Jul 2012 15:48:21 +0800	[thread overview]
Message-ID: <4FFD2FC5.2090701@cn.fujitsu.com> (raw)
In-Reply-To: <4FFD2F1E.10006@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.
