From: Zqiang Date: Mon, 11 Sep 2023 08:27:22 +0000 (+0800) Subject: workqueue: Fix missed pwq_release_worker creation in wq_cpu_intensive_thresh_init() X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=dd64c873ed11cdae340be06dcd2364870fd3e4fc;p=linux.git workqueue: Fix missed pwq_release_worker creation in wq_cpu_intensive_thresh_init() Currently, if the wq_cpu_intensive_thresh_us is set to specific value, will cause the wq_cpu_intensive_thresh_init() early exit and missed creation of pwq_release_worker. this commit therefore create the pwq_release_worker in advance before checking the wq_cpu_intensive_thresh_us.
