From f991b318cc6627a493b0d317a565bb7c3271f36b Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Tue, 21 Aug 2012 13:18:23 -0700 Subject: [PATCH] workqueue: clean up delayed_work initializers and add missing one Reimplement delayed_work initializers using new timer initializers which take timer flags. This reduces code duplications and will ease further initializer changes. This patch also adds a missing initializer - INIT_DEFERRABLE_WORK_ONSTACK().
