That's the definition all entry points for memory use KB as the unit.
so that's what you get in the driver and XML format files.

Your mail agent made garbage (nearly) of the patch, in the future

That variable is unused. Compiling the code show the warning. How did
you miss this ?

cleaned up the formatting, and removed the unused variable.
