the kernel (as opposed to building it as a module).
I do understand that loading the realtime lsm only does not create a
vulnerability (other than well known possibilities of DOS attacks by
mean linux audio users :-)
OK, that is a clearer explanation than mine ;-)
Anyway the kernel folks don't seem worried.
Spoke too soon. Here's the fix:
