I have run into this specific one before but failed to come up with a working fix. I think the specific warning started with https://lore.kernel.org/all/[email protected]/ but reverting that just replaces it with a slightly different warning. In my randconfig tree I have a patch that comments out the two security_task_getlsmprop_obj(), and I don't think I get warnings at the moment, but I no longer see why I would have done that. Arnd
