+         Unused but exported symbols make the kernel needlessly bigger.  For
+         that reason most of these unused exports will soon be removed.  This
+         option is provided temporarily to provide a transition period in case
+         some external kernel module needs one of these symbols anyway. If you
+         encounter such a case in your module, consider if you are actually
+         using the right API.  (rationale: since nobody in the kernel is using
+         this in a module, there is a pretty good chance it's actually the
+         wrong interface to use).  If you really need the symbol, please send a
+         mail to the linux kernel mailing list mentioning the symbol and why
+         you really need it, and what the merge plan to the mainline kernel for
+         your module is.
