Linus Torvalds 2013e8c2e6 Tracing fixes for 6.16: 
- Fix timerlat with use of FORTIFY_SOURCE
 
   FORTIFY_SOURCE was added to the stack tracer where it compares the
   entry->caller array to having entry->size elements.
 
   timerlat has the following:
 
      memcpy(&entry->caller, fstack->calls, size);
      entry->size = size;
 
   Which triggers FORTIFY_SOURCE as the caller is populated before the
   entry->size is initialized.
 
   Swap the order to satisfy FORTIFY_SOURCE logic.
 
 - Add down_write(trace_event_sem) when adding trace events in modules
 
   Trace events being added to the ftrace_events array are protected by
   the trace_event_sem semaphore. But when loading modules that have
   trace events, the addition of the events are not protected by the
   semaphore and loading two modules that have events at the same time
   can corrupt the list.
 
   Also add a lockdep_assert_held(trace_event_sem) to
   _trace_add_event_dirs() to confirm its held when iterating the list.

 - Fix timerlat with use of FORTIFY_SOURCE

   FORTIFY_SOURCE was added to the stack tracer where it compares the
   entry->caller array to having entry->size elements.

   timerlat has the following:

      memcpy(&entry->caller, fstack->calls, size);
      entry->size = size;

   Which triggers FORTIFY_SOURCE as the caller is populated before the
   entry->size is initialized.

   Swap the order to satisfy FORTIFY_SOURCE logic.

 - Add down_write(trace_event_sem) when adding trace events in modules

   Trace events being added to the ftrace_events array are protected by
   the trace_event_sem semaphore. But when loading modules that have
   trace events, the addition of the events are not protected by the
   semaphore and loading two modules that have events at the same time
   can corrupt the list.

   Also add a lockdep_assert_held(trace_event_sem) to
   _trace_add_event_dirs() to confirm it is held when iterating the
   list.
