From a81f80f3eb759de72d74d18e478873fc0575abc5 Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Fri, 16 Sep 2016 15:49:33 -0400 Subject: power, workqueue: remove keventd_up() usage Now that workqueue can handle work item queueing/cancelling from very early during boot, there is no need to gate cancel_delayed_work_sync() while !keventd_up(). Remove it. Signed-off-by: Tejun Heo Acked-by: Rafael J.
