From 5df9197edd731a44682444631d68c2384f381bf1 Mon Sep 17 00:00:00 2001 From: "Ricardo B. Marliere" Date: Tue, 6 Feb 2024 15:05:06 -0300 Subject: [PATCH] workqueue: make wq_subsys const Now that the driver core can properly handle constant struct bus_type, move the wq_subsys variable to be a constant structure as well, placing it into read-only memory which can not be modified at runtime.
