The stream's element is now the enum InotifyEvent, and the struct that describes a change to a watched item is FileSystemEvent. A queue overflow was an event with descriptor -1 and an empty path that every consumer had to know about; as a case, the compiler makes them handle it. The enum is also where failed watches of a growing tree will be reported, since no call site can catch them.
