Does this make torture.sh more reliably report build failures? Thanx, Paul ------------------------------------------------------------------------ commit 0d302830515307ceb58e89d5fb91e81b6d22e0bf Author: Paul E. McKenney <paulmck@xxxxxxxxxx> Date: Tue Jan 18 15:40:49 2022 -0800 torture: Make kvm-find-errors.sh notice missing vmlinux file Currently, an obtuse compiler diagnostic can fool kvm-find-errors.sh into believing that the build was successful. This commit therefore adds a check for a missing vmlinux file.
