Merge tag 'trace-fixes-v3.15-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace

Pull tracing fix from Steven Rostedt:
"This is a small fix where the trigger code used the wrong
rcu_dereference(). It required rcu_dereference_sched() instead of the
normal rcu_dereference(). It produces a nasty RCU lockdep splat due
to the incorrect rcu notation"
