Oh! And I just realise that's a new type; any reason for using `int` here (instead of `int64`)? 

Potentially this could even be an alias for the buildkit type (`cmd/buildkitd/config.HistoryConfig`), although if it becomes a public API, perhaps that `config` package should be moved outside of `cmd` as it looks it's no longer really a command-line config only (but options for a buildkit instance)
