I noticed the email but I wasn't sure if you knew
about the code from the way your mail was worded.
I used fasync and poll to implement user space
communications in a driver I just finished. Use
kill_fasync(&fasync, SIGIO) from the device driver to
signal the user app. The signal causes the app to poll
which the driver replies POLLIN to. Polling identifies
which device caused the signal. Now the user app knows
it needs to IOCTL the handle to do whatever the driver
needs it to. It only takes about 100 lines of code to
implement the communication.
google for: fasync sigio user
