Why do you want that? kernel drivers can't write to any filesystems, you should control the kernel from userspace. Only load your driver if you "know" you want to load it and have it control the hardware, no need to do anything strange in the kernel for something like this at all. good luck! greg k-h _______________________________________________ Kernelnewbies mailing list Kernelnewbies@xxxxxxxxxxxxxxxxx https://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
