Problem with EXPORT_SYMBOL(irq_to_desc)

[Prabhu nath <gprabhunath@xxxxxxxxx>]

Hi,

        I am facing a peculiar behaviour on Kernel version 2.6.34.1 (http://lxr.linux.no/#linux+v2.6.34.1). 
          
       For my experimentation I just wanted to use the following two kernel functions in my Kernel module

        1. find_task_by_vpid  (http://lxr.linux.no/#linux+v2.6.34.1/kernel/pid.c#L388)
        2. irq_to_desc  (http://lxr.linux.no/#linux+v2.6.34.1/kernel/irq/handle.c#L138)

           Since these two functions are not exported by the Kernel, I exported these functions, built the kernel and used in my kernel module. 
         When I compiled, I got a warning  "WARNING: "irq_to_desc" [/root/prabhu/KernelPrograms/irq/kmod.ko] undefined!"
         and when I inserted the module, I got error saying "kmod: Unknown symbol irq_to_desc"

         When I checked the object file pid.o, I found that find_task_by_vpid was placed in the Relocation section '.rel__ksymtab' and 
         when I checked the object file handle.o I found that irq_to_desc was not placed in the Relocation section '.rel__ksymtab'.

        Please help me in resolving this problem.

Regards
Prabhu
