From mboxrd@z Thu Jan 1 00:00:00 1970 From: Paul Gortmaker Subject: [PATCH net-next 3/3] tipc: remove redundant checking for the number of iovecs in a send request Date: Fri, 15 Feb 2013 17:57:47 -0500 Message-ID: <1360969067-29956-4-git-send-email-paul.gortmaker@windriver.com> References: <1360969067-29956-1-git-send-email-paul.gortmaker@windriver.com> Mime-Version: 1.0 Content-Type: text/plain Cc: , Jon Maloy , Ying Xue , Paul Gortmaker To: David Miller Return-path: Received: from mail1.windriver.com ([147.11.146.13]:38738 "EHLO mail1.windriver.com" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1752886Ab3BOW6J (ORCPT ); Fri, 15 Feb 2013 17:58:09 -0500 In-Reply-To: <1360969067-29956-1-git-send-email-paul.gortmaker@windriver.com> Sender: netdev-owner@vger.kernel.org List-ID: From: Ying Xue As the number of iovecs in a send request is already limited within UIO_MAXIOV(i.e. 1024) in __sys_sendmsg(), it's unnecessary to check it again in TIPC stack.
