Now, My problem is I don't have option to copy void * to void *, which is very important in my driver, why they removed such a beautiful option? Is there any other new functions are available? Is it possible to use same functions, then can any one have example to use of them? If you are using copyin()/copyout()/copyinstr() directly, rather than using uiomove()/uiomove64(), then you will need to make changes to your code. The reason for the change to the parameters was to support copying in/ out data with 64 bit user space addresses for 64 bit processes. Without the change, you would be limited to only passing data from the first 4G of process memory into the kernel when using a 64 bit process, and that wouldn't really be useful.
