[GIT PULL] tracing: A couple of fixes for 6.11

[Steven Rostedt]

Linus,

More tracing fixes for 6.11:

- Move declaration of interface_lock outside of CONFIG_TIMERLAT_TRACER

  The fix to some locking races moved the declaration of the
  interface_lock up in the file, but also moved it into the
  CONFIG_TIMERLAT_TRACER #ifdef block, breaking the build when
  that wasn't set. Move it further up and out of that #ifdef block.

- Remove unused function run_tracer_selftest() stub

  When CONFIG_FTRACE_STARTUP_TEST is not set the stub function
  run_tracer_selftest() is not used and clang is warning about it.
  Remove the function stub as it is not needed.

Note, I updated my test suite to test the case of OSNOISE tracer enabled
when the TIMERLAT tracer is not to catch the case that the one config not
enabled will not break the build again.
