What do you mean by this? You should be getting a callback with your kobject in it, so that you can then dig out the needed information to fill in the show/store data. But let's take a step back, what are you trying to do by creating a new sysfs directory? You should never create a subdir in the device tree in sysfs, that is not a 'struct device'. That is because udev / userspace will not see the directory, so any attribute under it will not be accessable by the tools that users use to access them. thanks, greg k-h _______________________________________________ devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxx http://driverdev.linuxdriverproject.org/mailman/listinfo/devel
