From 620d246065cdca4c4a8ad9ed28a191665cd3d457 Mon Sep 17 00:00:00 2001 From: "Paul E. McKenney" Date: Sat, 7 Jul 2018 18:25:10 -0700 Subject: [PATCH] rcuperf: Remove the "rcu_bh" and "sched" torture types Now that the RCU-bh and RCU-sched update-side functions are simple wrappers around their RCU counterparts, there isn't a whole lot of point in testing them. This commit therefore removes the "rcu_bh" and "sched" torture types from rcuperf. Signed-off-by: Paul E.
