From mboxrd@z Thu Jan 1 00:00:00 1970 From: Younger Liu Date: Thu, 1 Aug 2013 17:02:46 +0800 Subject: [Ocfs2-devel] [PATCH] ocfs2: free meta_ac and data_ac when ocfs2_start_trans fails in ocfs2_xattr_set() Message-ID: <51FA2436.2050604@huawei.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: ocfs2-devel@oss.oracle.com In ocfs2_xattr_set(), if ocfs2_start_trans failed, meta_ac and data_ac should be free. Otherwise, It would lead to memory leak.
