You might want to update this sentence a bit. Something like:
Per VM BOs must be marked as moved or otherwise their ranges are not
updated on use
If the BO has been moved the PT should be updated, otherwise the VAs
might point to invalid PT.
This fixes random GPU hangs when replacing sparse mappings from the
userspace, while OP_MAP/OP_UNMAP works fine because always valid BOs
are correctly handled there.
