This commit adds a kvm-series.sh script that takes a list of scenarios and a list of commits, and then runs each scenario on all of the commits. A given scenario is run on all the commits before advancing to the next scenario to minimize build times. The successes and failures are summarized at the end of the run. Signed-off-by: Paul E. McKenney <paulmck@kernel.org> Signed-off-by: Frederic Weisbecker <frederic@kernel.org>
