Linus Torvalds cccf0c2ee5 Tracing updates for 6.5:
- Add new feature to have function graph tracer record the return value.
   Adds a new option: funcgraph-retval ; when set, will show the return
   value of a function in the function graph tracer.
 
 - Also add the option: funcgraph-retval-hex where if it is not set, and
   the return value is an error code, then it will return the decimal of
   the error code, otherwise it still reports the hex value.
 
 - Add the file /sys/kernel/tracing/osnoise/per_cpu/cpu<cpu>/timerlat_fd
   That when a application opens it, it becomes the task that the timer lat
   tracer traces. The application can also read this file to find out how
   it's being interrupted.
 
 - Add the file /sys/kernel/tracing/available_filter_functions_addrs
   that works just the same as available_filter_functions but also shows
   the addresses of the functions like kallsyms, except that it gives the
   address of where the fentry/mcount jump/nop is. This is used by BPF to
   make it easier to attach BPF programs to ftrace hooks.
 
 - Replace strlcpy with strscpy in the tracing boot code.
