+ * that with a printf "%s" instead of saving the string in the ring buffer
+ * and wasting space and time.

+ * 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

+ * to be used with modules, because when modules are unloaded, if they
