Subject: Getting data from other process when running in kernel thread

Hi,
I have following problem when running in a kernel thread. I know the pid of a 
program which started some data processing. After I finished with it, it 
should send the data to the user process and/or getting new data from it. This 
means that I must use copy_from_user/copy_to_user, but with specifying the 
pid/task.

Is that somehow possible? I think most of the things are done in workqueues 
and so I don't really know in which context I am.

Best regards,
	Resul Cetin
