From eac0337af12b6a55f08c69429400d6530d602dff Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Fri, 16 Sep 2016 15:49:34 -0400 Subject: slab, workqueue: remove keventd_up() usage Now that workqueue can handle work item queueing from very early during boot, there is no need to gate schedule_delayed_work_on() while !keventd_up(). Remove it.
