From 0687c66b5f666b5ad433f4e94251590d9bc9d10e Mon Sep 17 00:00:00 2001 From: Zqiang Date: Thu, 18 Feb 2021 11:16:49 +0800 Subject: workqueue: Move the position of debug_work_activate() in __queue_work() 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.
