I wouldn't use this wording, as it implies a specific implementation.  Fi_cancel does not generate a completion entry itself.  It attempts to change the state of some other operation, which may or may not be found, and may or may not allow the state change.  But if the request is canceled, the information you gave regarding the CQ is correct.
