From fd30b717b86dc30ffe25596f8de6542a02ae9401 Mon Sep 17 00:00:00 2001 From: Kees Cook Date: Sun, 22 Oct 2017 17:58:54 -0700 Subject: rcu: Convert timers 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.
