From 8c20feb60604d91a29cd7fef8ac758bd92d9fd2c Mon Sep 17 00:00:00 2001 From: Kees Cook Date: Wed, 4 Oct 2017 16:27:07 -0700 Subject: workqueue: Convert callback to use from_timer() In preparation for unconditionally passing the struct timer_list pointer to all timer callbacks, switch workqueue to use from_timer() and pass the timer pointer explicitly.
