Message-ID: <1425023818-12880-2-git-send-email-erik.hugne@ericsson.com> Date: Fri, 27 Feb 2015 08:56:54 +0100 From: <erik.hugne@...csson.com> To: <netdev@...r.kernel.org> CC: <tipc-discussion@...ts.sourceforge.net>, <jon.maloy@...csson.com>, <richard.alpe@...csson.com>, <ying.xue@...driver.com>, Erik Hugne <erik.hugne@...csson.com> Subject: [PATCH net-next v2 1/5] tipc: only create header copy for name distr messages From: Erik Hugne <erik.hugne@...csson.com> The TIPC name distributor pushes topology updates to the cluster neighbors. Currently this is done in a unicast manner, and the skb holding the update is cloned for each cluster member. This is unnecessary, as we only modify the destnode field in the header so we change it to do pskb_copy instead.
