    SubjectI/O operations priority in RTOS
    I'm studying how to develop drivers in a real time OS and how do they
    work. I'm using Ubuntu 10.04 with the 2.6.31-11-rt patch installed.
    I would like to know the priority when executing open(), read(), write()
    and close() operations.
    In my example the thread which is using the driver runs with 10 RTPRIO,
    but I don't know what happens in kernel context with the priority when
    running the I/O operations.
    Thank you for your help, I don't know where to learn about this.
