Steven Rostedt (Red Hat) 5d6c97c559 tracing: Do not try to recreated toplevel set_ftrace_* files ... With the restructing of the function tracer working with instances, the "top level" buffer is a bit special, as the function tracing is mapped to the same set of filters. This is done by using a "global_ops" descriptor and having the "set_ftrace_filter" and "set_ftrace_notrace" map to it. When an instance is created, it creates the same files but its for the local instance and not the global_ops. The issues is that the local instance creation shares some code with the global instance one and we end up trying to create th top level "set_ftrace_*" files twice, and on boot up, we get an error like this: Could not create debugfs 'set_ftrace_filter' entry Could not create debugfs 'set_ftrace_notrace' entry The reason they failed to be created was because they were created twice, and the second time gives this error as you can not create the same file twice.
