Hi Hellwig,

Sorry, maybe I misunderstood your point. Do you mean the exported symbol
below? They are used by the vfio_iommu_type1 driver which is a separate
driver besides the vfio.ko driver.

+EXPORT_SYMBOL_GPL(vfio_mm_put);
+EXPORT_SYMBOL_GPL(vfio_mm_get_from_task);
+EXPORT_SYMBOL_GPL(vfio_mm_pasid_alloc);
+EXPORT_SYMBOL_GPL(vfio_mm_pasid_free);

Regards,
Yi Liu
