[PATCH 5.4 084/111] workqueue: Move the position of debug_work_activate() in __queue_work()

[Greg Kroah-Hartman]

From: Zqiang <qiang.zhang@xxxxxxxxxxxxx>

[ Upstream commit 0687c66b5f666b5ad433f4e94251590d9bc9d10e ]

The debug_work_activate() is called on the premise that
the work can be inserted, because if wq be in WQ_DRAINING
status, insert work may be failed.

Fixes: e41e704bc4f4 ("workqueue: improve destroy_workqueue() debuggability")
