Prev: [PATCH RFC tip/core/rcu 08/10] rcu: rename rcutiny rcu_ctrlblk to rcu_sched_ctrlblk
Next: [PATCH RFC tip/core/rcu 02/10] rcu: make dead code really dead
From: Paul E. McKenney on 5 Apr 2010 14:40 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.
