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
