About EXPORT_SYMBOL

Hello All, I want to export a function named ext2_free_data() which is present in inode.c . This function is statically defined in this file. I omit the "static" keyword and exported it using EXPORT_SYMBOL(ext2_free_data). ext2_free_data() function declaration is not present in any header file , so I included its declaration in my own header file which I kept in fs/ext2 directory. Now when I insert my module using insmod command ,it shows a error : Unknown symbol in module. Kindly help me . -- Regards, Kashish
