The problem is that various static inline functions such as
reservation_object_fini() indirectly call mutex_destroy.  On DEBUG_MUTEX
kernels, mutex_destroy is EXPORT_SYMBOL_GPL.

So your problem is simply that your non-GPL module can't link anymore
with -RT.  Would it help you if I simply replace the export for
mutex_destroy with EXPORT_SYMBOL and leave it the function as is?

Yes, definitely.

Thanks,
