Zongxun Wang fb951eb5e1 ocfs2: free allocated clusters if error occurs after ocfs2_claim_clusters ... Even if using the same jbd2 handle, we cannot rollback a transaction. So once some error occurs after successfully allocating clusters, the allocated clusters will never be used and it means they are lost. For example, call ocfs2_claim_clusters successfully when expanding a file, but failed in ocfs2_insert_extent. So we need free the allocated clusters if they are not used indeed.
