+ The "print fmt" of the trace events will show the enum names instead
+ of their values. This can cause problems for user space tools that
+ use this string to parse the raw data as user space does not know
+ how to convert the string to its value.
+
+ To fix this, there's a special macro in the kernel that can be used
+ to convert the enum into its value. If this macro is used, then the
+ print fmt strings will have the enums converted to their values.
+
+ If something does not get converted properly, this option can be
+ used to show what enums the kernel tried to convert.
+
+ This option is for debugging the enum conversions. A file is created
+ in the tracing directory called "enum_map" that will show the enum
+ names matched with their values and what trace event system they
+ belong too.
+
+ Normally, the mapping of the strings to values will be freed after
+ boot up or module load. With this option, they will not be freed, as
+ they are needed for the "enum_map" file. Enabling this option will
+ increase the memory footprint of the running kernel.
