From 94162c8daa839bd0de791f66d754a880e2787c82 Mon Sep 17 00:00:00 2001 From: "Paul E. McKenney" Date: Wed, 10 Dec 2014 17:42:16 -0800 Subject: rcutorture: Handle different mpstat versions The mpstat command recently added the %gnice column, which messes up the cpu2use.sh script's idle-CPU calculations. This commit therefore uses $NF instead of $12 to select the last (%idle) column. Signed-off-by: Paul E.
