    Linux kernel programming

    Hi all,
    I m new to kernel programming. I am into block device drivers now.
    I have written a kernel module that does a mirroring action between 2 scsi disks. Its working fine.
    Now i want that module to be called from interrupt level using a system call.
    I Should write a user space program to create a system call that initiates my disk_copy.c

    I need some inputs.
    Please help.

    Thanks
    -Nakul Sargur

    I've never done such a thing but have you looked at this:

    Implementing Linux System Calls | Linux Journal

    Alternatively, you could give your existing module some kind of /dev interface with a protocol for triggering events, and perhaps a userspace lib that implements the protocol.

    C programming resources:
    GNU C Function and Macro Index -- glibc reference manual
    The C Book -- nice online learner guide
    Current ISO draft standard
    CCAN -- new CPAN like open source library repository
    3 (different) GNU debugger tutorials: #1 -- #2 -- #3
    cpwiki -- our wiki on sourceforge
