Steven Rostedt (VMware) 0948d6294d ftrace: Protect ftrace_graph_hash with ftrace_sync 
[ Upstream commit 54a16ff6f2e50775145b210bcd94d62c3c2af117 ]

As function_graph tracer can run when RCU is not "watching", it can not be
protected by synchronize_rcu() it requires running a task on each CPU before
it can be freed. Calling schedule_on_each_cpu(ftrace_sync) needs to be used.
