[PATCH] virtio: make virtio_bus const

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]


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.
