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.
