[PATCH tip/core/rcu 02/26] torture: Add "scenarios" option to kvm.sh --dryrun parameter

From: Paul E. McKenney
Date: Tue May 11 2021 - 19:12:34 EST


This commit adds "--dryrun scenarios" to kvm.sh, which prints something
like this:

1. TREE03
2. TREE07
3. SRCU-P SRCU-N
4. TREE01 TRACE01
5. TREE02 TRACE02
6. TREE04 RUDE01 TASKS01
7. TREE05 TASKS03 SRCU-T SRCU-U
8. TASKS02 TINY01 TINY02 TREE09

This format is more convenient for scripts that run batches of scenarios.
