From 06ca91448f32247c436e83116357f891be03b4bd Mon Sep 17 00:00:00 2001 From: "Paul E. McKenney" Date: Fri, 9 Jul 2021 17:13:34 -0700 Subject: [PATCH] torture: Make kvm-test-1-run-qemu.sh check for reboot loops It turns out that certain types of early boot bugs can result in reboot loops, even within a guest OS running under qemu/KVM. This commit therefore upgrades the kvm-test-1-run-qemu.sh script's hang-detection heuristics to detect such situations and to terminate the run when they occur. Signed-off-by: Paul E.
