Subject: [PATCH] workqueue: Move the position of debug_work_activate() in __queue_work()
Date: Thu, 11 Feb 2021 16:23:51 +0800 [thread overview]
Message-ID: <20210211082351.178536-1-qiang.zhang@windriver.com> (raw)
From: Zqiang <qiang.zhang@windriver.com>
The debug_work_activate() is called on the premise that
the work can be inserted, because if wq be in WQ_DRAINING
