Merge tag 'trace-v4.12-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace
Pull tracing fixes from Steven Rostedt: - Fix a bug caused by not cleaning up the new instance unique triggers when deleting an instance. It also creates a selftest that triggers that bug. - Fix the delayed optimization happening after kprobes boot up self tests being removed by freeing of init memory. - Comment kprobes on why the delay optimization is not a problem for removal of modules, to keep other developers from searching that riddle. - Fix another case of rcu not watching in stack trace tracing. * tag 'trace-v4.12-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: tracing: Make sure RCU is watching before calling a stack trace kprobes: Document how optimized kprobes are removed from module unload selftests/ftrace: Add test to remove instance with active event triggers selftests/ftrace: Fix bashisms ftrace: Remove #ifdef from code and add clear_ftrace_function_probes() stub ftrace/instances: Clear function triggers when removing instances ftrace: Simplify glob handling in unregister_ftrace_function_probe_func() tracing/kprobes: Enforce kprobes teardown after testing tracing: Move postpone selftests to core from early_initcall
