From a2d812a27a4530b999a92f245d0d8291663e8c38 Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Fri, 18 May 2018 08:47:13 -0700 Subject: workqueue: Make worker_attach/detach_pool() update worker->pool For historical reasons, the worker attach/detach functions don't currently manage worker->pool and the callers are manually and inconsistently updating it. This patch moves worker->pool updates into the worker attach/detach functions. This makes worker->pool consistent and clearly defines how worker->pool updates are synchronized. This will help later workqueue visibility improvements by allowing safe access to workqueue information from worker->task.
