From 2bccef39c0d94b9ee428ae777c59cef1fced786c Mon Sep 17 00:00:00 2001 From: Kees Cook Date: Tue, 17 Oct 2017 20:33:01 -0700 Subject: drbd: 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.
