From mboxrd@z Thu Jan 1 00:00:00 1970 From: Pablo Neira Ayuso Subject: [PATCH 23/25] netfilter: h323: Use mod_timer instead of set_expect_timeout Date: Sat, 23 Jul 2016 13:08:37 +0200 Message-ID: <1469272119-29942-24-git-send-email-pablo@netfilter.org> References: <1469272119-29942-1-git-send-email-pablo@netfilter.org> Cc: davem@davemloft.net, netdev@vger.kernel.org To: netfilter-devel@vger.kernel.org Return-path: In-Reply-To: <1469272119-29942-1-git-send-email-pablo@netfilter.org> Sender: netdev-owner@vger.kernel.org List-Id: netfilter-devel.vger.kernel.org From: Gao Feng Simplify the code without any side effect. The set_expect_timeout is used to modify the timer expired time. It tries to delete timer, and add it again. So we could use mod_timer directly.
