What do you want to do with that kobject_uevent() function? Almost all of the functionality is still there, with the exception that you don't provide the attribute anymore. But, you can now poll an attribute from userspace properly, so you might just look into doing that instead (you need to change your kernel code a bit to use it though.) thanks, greg k-h -- Kernelnewbies: Help each other learn about the Linux kernel.
