kernel/module.c warning re: non-GPL modules looks wrong

[Robert P. J. Day]

  from kernel/module.c:
...
        ks = lookup_symbol(name, __start___ksymtab_gpl_future,
                                 __stop___ksymtab_gpl_future);
        if (ks) {
                if (!gplok) {
                        printk(KERN_WARNING "Symbol %s is being used "
                          "by a non-GPL module, which will not "
                          "be allowed in the future\n", name);
                        printk(KERN_WARNING "Please see the file "
                          "Documentation/feature-removal-schedule.txt "
                          "in the kernel source tree for more "
                          "details.\n");
...

  but there's nothing in the feature removal file that expands on that
issue.  (there *is* an entry regarding *unused* symbols, but that
doesn't seem to address the above.)

EXPORT_GPL_FUTURE is used to mark _functionality_ as no longer available
after a grace period. So when one marks a set of symbols as GPL_FUTURE
that functionality ougt to be described in feature-removal.
Did you see any _functionaliy_ where GPL_FUTURE are used where it
is not warned in fetaure-removal that that _functionality_ are supposed
to be changed?

Or in other words - please be more specific.
