McKenney" List-Id: linux-arch.vger.kernel.org Currently, cmplitmushist.sh treats timeouts (as in the "--timeout" argument) as "Missing Observation line". This can be misleading because it is quite possible that running the test longer would have produced a verification. This commit therefore changes cmplitmushist.sh to check for timeouts and to report them with "Timed out". Signed-off-by: Paul E.
