Verification error". This can be misleading because it fails to call out typos and running a version LKMM on a litmus test requiring a feature not provided by that version. This commit therefore changes judgelitmus.sh to check for unknown primitives and to report them, for example, with: '!!! Current LKMM version does not know "rcu_write_lock"'. Signed-off-by: Paul E.
