From 96d1327ac2e3dc3ac4204fe3656dad0043fc0efd Mon Sep 17 00:00:00 2001 From: Gao Feng Date: Fri, 22 Jul 2016 12:59:15 +0800 Subject: netfilter: h323: Use mod_timer instead of set_expect_timeout 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.
