Steven Rostedt 1eab6493f5 tracing: Documentation: Update histogram-design.rst for fn() handling ... The histogram documentation describes the old method of the histogram triggers using the fn() field of the histogram field structure to process the field. But due to Spectre mitigation, the function pointer to handle the fields at runtime caused a noticeable overhead. It was converted over to a fn_num and hist_fn_call() is now used to call the specific functions for the fields via a switch statement based on the field's fn_num value. Update the documentation to reflect this change.
