In-Reply-To: <20080228024155.GA9569@tma-pc1.cn.oracle.com> References: <20080228024155.GA9569@tma-pc1.cn.oracle.com> Message-ID: <47C6225E.5020107@oracle.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: ocfs2-devel@oss.oracle.com Actually this is already in the last set of dlm patches. The one I missed was dlm_lock_add_to_array(). http://oss.oracle.com/pipermail/ocfs2-devel/2008-February/001847.html Make a patch just for that and we can add that in the checkin queue.
