From f71d8311ec278525508dac211de700b2b682a15f Mon Sep 17 00:00:00 2001 From: "Paul E. McKenney" Date: Wed, 17 Jun 2020 12:06:47 -0700 Subject: refscale: Change --torture type from refperf to refscale This commit renames the rcutorture config/refperf to config/refscale to further avoid conflation with the Linux kernel's perf feature.
