* tracepoint_string - register constant persistent string to trace system
* @str - a constant persistent string that will be referenced in tracepoints
*
* If constant strings are being used in tracepoints, it is faster and
* more efficient to just save the pointer to the string and reference
* that with a printf "%s" instead of saving the string in the ring buffer
* and wasting space and time.
*
* The problem with the above approach is that userspace tools that read
* the binary output of the trace buffers do not have access to the string.
* Instead they just show the address of the string which is not very
* useful to users.
*
* With tracepoint_string(), the string will be registered to the tracing
* system and exported to userspace via the debugfs/tracing/printk_formats
* file that maps the string address to the string text. This way userspace
* tools that read the binary buffers have a way to map the pointers to
* the ASCII strings they represent.
*
* The @str used must be a constant string and persistent as it would not
* make sense to show a string that no longer exists. But it is still fine
* to be used with modules, because when modules are unloaded, if they
* had tracepoints, the ring buffers are cleared too. As long as the string
* does not change during the life of the module, it is fine to use
* tracepoint_string() within a module.
