[PATCH tip/core/rcu 02/20] torture: Make kvm.sh "--dryrun sched" summarize number of batches
From: paulmck
Date: Wed Jan 06 2021 - 12:26:51 EST
From: "Paul E. McKenney" <paulmck@xxxxxxxxxx>
Knowing the number of batches that kvm.sh will split a run into allows
estimation of the duration of a test, give or take the number of builds.
This commit therefore adds a line of output to "--dryrun sched" that
gives the number of batches that will be run.
