    Hi,
       I am inserting a module(device driver) using insmod. I want to send
    a message from this module to an user process. For this I used msgsnd
    with buffer in the call as a local variable. I am getting an error
    "EFAULT" for this call. However this did not happen when I made the
    driver code as a part of kernel and not as a module. Any idea about
    what could be the problem and how to solve it?

    TIA

    Regards,
    Seenu.
