From mboxrd@z Thu Jan 1 00:00:00 1970 From: Jon Maloy Subject: [PATCH net-next v2 02/14] tipc: move code for resetting links from bearer.c to link.c Date: Thu, 13 Feb 2014 17:29:06 -0500 Message-ID: <1392330558-19048-3-git-send-email-jon.maloy@ericsson.com> References: <1392330558-19048-1-git-send-email-jon.maloy@ericsson.com> Cc: netdev@vger.kernel.org, Paul Gortmaker , erik.hugne@ericsson.com, ying.xue@windriver.com, maloy@donjonn.com, tipc-discussion@lists.sourceforge.net, Jon Maloy To: davem@davemloft.net Return-path: Received: from smtp103.biz.mail.ne1.yahoo.com ([98.138.207.10]:20953 "HELO smtp103.biz.mail.ne1.yahoo.com" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with SMTP id S1752471AbaBMW3d (ORCPT ); Thu, 13 Feb 2014 17:29:33 -0500 In-Reply-To: <1392330558-19048-1-git-send-email-jon.maloy@ericsson.com> Sender: netdev-owner@vger.kernel.org List-ID: From: Ying Xue We break out the code for resetting attached links in the function tipc_reset_bearer(), and define a new function named tipc_link_reset_list() to do this job. This commit incurs no functional changes, but makes the code of function tipc_reset_bearer() cleaner. It is also a preparation for a more important change to the bearer code, in a subsequent commit in this series.
