kernel hooks interface available to non-GPL modules?

kernel hooks interface available to non-GPL modules?

+EXPORT_SYMBOL(hook_exit_deregister);
+EXPORT_SYMBOL(hook_exit_arm);
+EXPORT_SYMBOL(hook_exit_disarm);
+EXPORT_SYMBOL(_hook_initialise);
+EXPORT_SYMBOL(_hook_terminate);
+EXPORT_SYMBOL(_hook_exit_register);

I'm not sure this is a great idea.  OK, your DECLARE_HOOK macros are _GPL
(and why are they _NOVERS_GPL?  Surely this is the exact kind of thing
you want versioned?), but I wouldn't have to use the DECLARE_HOOK macros,
would I?

If you thought the LSM GPL furore was bad, this one would be worse.

I agree and have exported hook interfaces with _GPL in the latest version of
the patch. It will be at http://www-124.ibm.com/linux/patches/?patch_id=595.
