From e7c2f967445dd2041f0f8e3179cca22bb8bb7f79 Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Tue, 21 Aug 2012 13:18:24 -0700 Subject: workqueue: use mod_delayed_work() instead of __cancel + queue Now that mod_delayed_work() is safe to call from IRQ handlers, __cancel_delayed_work() followed by queue_delayed_work() can be replaced with mod_delayed_work(). Most conversions are straight-forward except for the following. * net/core/link_watch.c: linkwatch_schedule_work() was doing a quite elaborate dancing around its delayed_work. Collapse it such that linkwatch_work is queued for immediate execution if LW_URGENT and existing timer is kept otherwise. Signed-off-by: Tejun Heo Cc: "David S.
