Cause it’s overkill. There is no hardware/abstract device connection between an overlay and a device as what’s being used right now in driver core. kobjs are enough to present them in the filesystem hierarchy. > Why even have them in sysfs at all?

That’s what’s possible for now; in the future we might present the full contents of the overlay there, and what changes to the live tree were made. > thanks, > > greg k-h Regards — Pantelis -- 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/
