Wait, you are mixing a class and a "real" bus up. This will fail as your devices all end up on the virtual "bus" with the same name, in the same location on the bus (look in /sys/devices/virtual/ for where they will end up at. That will fail, and rightly so. Try using this with the proper 'struct bus_type' and let me know if creating a device there with the same name will also fail. Oh crud, it will, because we can't create symlinks with the same bus type in the /sys/bus/BUSTYPE/devices/ directory. So, don't use the same name for a device on the same bus, that way causes confusion :) Let's get back to your original "problem", what again are you trying to solve? There should be a way to resolve this without having to deal with duplicate names, perhaps you just want an attribute group with a common name? thanks, greg k-h -- 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/
