From 7b5470bace024bb8dc4c161088770aea4775843f Mon Sep 17 00:00:00 2001 From: "Paul E. McKenney" Date: Mon, 13 Jan 2014 23:16:55 -0800 Subject: [PATCH] rcutorture: Allow kvm-test-1-rcu.sh to pause after build Parallel rcutorture runs is valuable on large systems, but it is not a good idea to do (say) five builds in parallel if each build believes it has the whole system at its disposal, especially if the system is shared. It is also bad to restrict the build to (say) a single CPU just because the corresponding rcutorture run uses only a single CPU. This commit therefore adds a kvm-test-1-rcu.sh ability to pause after the build completes, which will allow kvm.sh to do a number of builds serially (with each build thus having the full system at its disposal), then allow the rcutorture runs to proceed in parallel.
