McKenney" <paulmck@...ux.vnet.ibm.com> Subject: [PATCH RFC tip/core/rcu 06/10] rcu: fix now-bogus rcu_scheduler_active comments. The rcu_scheduler_active check has been wrapped into the new debug_lockdep_rcu_enabled() function, so update the comments to reflect this new reality. Signed-off-by: Paul E.
