Subject: [PATCH] workqueue: Convert timers to use timer_setup() (part 2)
Date: Mon, 16 Oct 2017 15:58:25 -0700 [thread overview]
Message-ID: <20171016225825.GA99101@beast> (raw)
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. (The prior workqueue
patch missed a few timers.)
