From 9c6c273aa4248c60569de6ef7e7e9c7bed3cd32e Mon Sep 17 00:00:00 2001 From: Kees Cook Date: Wed, 4 Oct 2017 16:26:57 -0700 Subject: timer: Remove init_timer_on_stack() in favor of timer_setup_on_stack() Remove uses of init_timer_on_stack() with open-coded function and data assignments that could be expressed using timer_setup_on_stack(). Several were removed from the stack entirely since there was a one-to-one mapping of parent structure to timer, those are switched to using timer_setup() instead. All related callbacks were adjusted to use from_timer().
