Hi all!
I've modified a standard driver and now I'd like to create a FIFO in
it to communicate / send data to a userland process.
Opening, reading and writing to a FIFO in userland is easy, but I have
no clue how to do this in kernel space. Googling and looking to the
kernel source didn't help.

Thanks for your reply! :-)
Well, the reason why I want to use a true FIFO is, that data is
sampled i.e. every second and I want to write it to disk in userspace
only every minute or so. So if I
