From 99767f278ccf74a1857069bb3eec991e572f94cd Mon Sep 17 00:00:00 2001 From: Kees Cook Date: Mon, 16 Oct 2017 17:29:36 -0700 Subject: net/core: Convert sk_timer users to use timer_setup() In preparation for unconditionally passing the struct timer_list pointer to all timer callbacks, switch to using the new timer_setup() and from_timer() to pass the timer pointer explicitly for all users of sk_timer.
