No, have userspace allocate the memory, pass it to the kernel, fill it up, and then pass it back. Much easier that way. Or use configfs/sysfs, passing structures in and out of the kernel is not recommended for a large number of very good reasons (not the least being 32/64bit reasons). good luck, greg k-h -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to ecartis@xxxxxxxxxxxx Please read the FAQ at http://kernelnewbies.org/FAQ
