Just to be clear, What do you mean by current process. Is it the process
which is executing the kernel module? That would be a kernel thread I
believe or do you want to be able to set the cpu affinity for any
process given its PID? 
And are you looking at setting CPU affinity of kernel threads or user

Thank you
