From f5f654096487c6d526c47bb66308f9de81f091cf Mon Sep 17 00:00:00 2001 From: "Paul E. McKenney" Date: Thu, 25 Feb 2010 19:02:30 -0800 Subject: rcu: Export rcu_scheduler_active Kernel modules using rcu_read_lock_sched_held() must now have access to rcu_scheduler_active, so it must be exported. This should fix the fix for the boot-time RCU-lockdep splat. Signed-off-by: Paul E.
