It would be simple enough to grep the names of all the UAPI struct and use pahole to make a list of the existing structs which have holes. Then re-run the script every week and complain when new holey struct types are added. You could do a similar thing with Smatch looking at copy_to/from_user() struct types. regards, dan carpenter
