Steven Rostedt (VMware) 0948d6294d ftrace: Protect ftrace_graph_hash with ftrace_sync ... [ Upstream commit 54a16ff6f2 ] 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.
