+         The STACKLEAK gcc plugin instruments the kernel code for tracking
+         the lowest border of the kernel stack (and for some other purposes).
+         It inserts the stackleak_track_stack() call for the functions with
+         a stack frame size greater than or equal to this parameter.
+         If unsure, leave the default value 100.
