From 2b666ee29618f452b84aeacf08e1267894de7234 Mon Sep 17 00:00:00 2001 From: "Ricardo B. Marliere" Date: Sun, 4 Feb 2024 17:52:51 -0300 Subject: [PATCH] virtio: make virtio_bus const Now that the driver core can properly handle constant struct bus_type, move the virtio_bus variable to be a constant structure as well, placing it into read-only memory which can not be modified at runtime.
