Merge tag 'ftrace-v6.16-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace

Pull ftrace fix from Steven Rostedt:

 - Do not blindly enable function_graph tracer when updating
   funcgraph-args

   When the option to trace function arguments in the function graph
   trace is updated, it requires the function graph tracer to switch its
   callback routine. It disables function graph tracing, updates the
   callback and then re-enables function graph tracing.

   The issue is that it doesn't check if function graph tracing is
   currently enabled or not. If it is not enabled, it will try to
   disable it and re-enable it (which will actually enable it even
   though it is not the current tracer). This causes an issue in the
   accounting and will trigger a WARN_ON() if the function tracer is
   enabled after that.
