    Hi,
         I am writing a module, that communicates to the other module by
    queues. I am using sys_msgget and related functions. I have assumed, if
    the symbol is present on /proc/kallsyms then the other modules can
    refer symbol. For an example, the sys_msgget is appeared on the
    symboltable. But it is not exported by any one of the
    files(EXPORT_SYMBOL). So when i tried to use the sys_msgget to create a
    message queue, my module was compiled with the warning and it never
    loaded with insmod. It always says it could not resove the symbol
    sys_msgget.
             So i added EXPORT_SYMBOL(sys_msgget) in
    arch/arm/kernel/armksyms.c. then build the image and my module. Then
    the insmod works with my module without any problem.
      My question is that can i do this way??. Can i use sys_msgget in
    module programming??. Since it is not explicitly exported i have the
    doubhts.
