McKenney <paulmck@xxxxxxxxxxxxxxxxxx> CommitDate: Tue, 14 Jun 2016 16:02:15 -0700 torture: Simplify code, eliminate RCU_PERF_TEST_RUNNABLE This commit applies the infamous IS_ENABLED() macro to eliminate a #ifdef. It also eliminates the RCU_PERF_TEST_RUNNABLE Kconfig option in favor of the already-existing rcuperf.perf_runnable kernel boot parameter. Signed-off-by: Paul E.
