From 2528dcbea94496f080aad9311327baedc11831d7 Mon Sep 17 00:00:00 2001 From: "Ricardo B. Marliere" Date: Sat, 3 Feb 2024 15:53:37 -0300 Subject: [PATCH] xen: pcpu: make xen_pcpu_subsys const Now that the driver core can properly handle constant struct bus_type, move the xen_pcpu_subsys variable to be a constant structure as well, placing it into read-only memory which can not be modified at runtime.
