    help needed: adding a new filesystem module

    I'm a student and new to knoppix.
    My project is to add a new filesystem based on ext2 to the kernel as a module.
    In the file namei.c of the ext2 filesystem I inserted the open_namei system call.
    the compilation went OK, but when I tried to run insmod, the following error appeared:

    extv.o: extv.o: unresolved symbol open_namei

    I understand that I need to add EXPORT_SYMBOL(open_namei); somewhere, but where???

    I'm using the Knoppix CD, so I can't change the /usr/src/fs/namei.c (because it's not there, and because the /usr/src is on read-only filesystem...

    Thanks in advance,
    Shabi

    re

    after adding a module, I think you must do (as root)

    Code:
    ldconfig
    updatedb
    depmod -a

    Good Luck
