net-sysfs: warn if new queue objects are being created during device unregistration
Calling netdev_queue_update_kobjects is allowed during device unregistration since commit 5c56580b ("net: Adjust TX queue kobjects if number of queues changes during unregister"). But this is solely to allow queue unregistrations. Any path attempting to add new queues after a device started its unregistration should be fixed. This patch adds a warning to detect such illegal use. Signed-off-by: Antoine Tenart <atenart@kernel.org> Signed-off-by: Jakub Kicinski <kuba@kernel.org>
