McKenney" This commit adds a kvm-check-branches.sh script that takes a list of commits and commit ranges and runs a short rcutorture test on all scenarios on each specified commit. A summary is printed at the end, and the script returns success if all rcutorture runs completed without error. Signed-off-by: Paul E.
