Umm, this replaces alloc_chrdev_region too. If instead you mean "let's migrate all the users to a sensible interface", I agree. And that means killing alloc_chrdev_region too. (baseminor makes no sense for dynamic allocation - you either know your prefered major and minor or you know neither.) > - /proc/devices.

I think killing /proc/devices has to wait until after devfs removal, when everyone is more or less comfortable with its alternatives. -- Mathematics is the supreme nostalgia of our time. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
