From: Gerrit Renker Date: Thu, 05 Apr 2007 15:36:54 +0000 Subject: [PATCH 35/43]: Reduce the number of writable states Message-Id: <200704051636.54136@strip-the-willow> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: dccp@vger.kernel.org [DCCP]: Reduce the number of writable states Since DCCP requires to close both ends of a connection simultaneously, permission to write in state DCCP_CLOSING is removed in dccp_sendmsg(): * if the sending end closed, it would encounter a write error anyhow; * if the other end has closed the connection, it accepts no more data.
