From fcb58a033271e448c3e49a3b3d3e9e0c0bcf61d9 Mon Sep 17 00:00:00 2001 From: Jozsef Kadlecsik Date: Thu, 10 Nov 2016 12:32:07 +0100 Subject: [PATCH] netfilter: ipset: use setup_timer() and mod_timer(). Use setup_timer() and instead of init_timer(), being the preferred way of setting up a timer. Also, quoting the mod_timer() function comment: -> mod_timer() is a more efficient way to update the expire field of an active timer (if the timer is inactive it will be activated). Use setup_timer() and mod_timer() to setup and arm a timer, making the code compact and easier to read.
