OK, so the default behaviour is unchanged and users opt into the new behaviour by providing this module parameter? Why is this worth doing? What behaviour changes would users see if we defaulted to dynamic minors? I'm surprised we don't have some library code somewhere for managing a map of minor numbers - it's an operation which is common to so many drivers. It would be bitmap or IDR based, I expect. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
