[openib-general] .toc is not generated for indexing service module

[Heiko J Schick]

Hello Sean,

it seems that the "indexing service" module (index.c) doesn't call any
external functions. In that case, the .toc will not be generated on PPC64
and the file linux/arch/powerpc/kernel/module_64.c will not load the module,
because of a missing .toc entry in the ELF section. You can see it in the
following output:

# insmod findex.ko
insmod: error inserting 'findex.ko': -1 Invalid module format

# dmesg
[244975.787887] findex: doesn't contain .toc or .stubs.

As first workaround I would propose to include printk() to the function
index_start. We will have then an external function call and the .toc will
be generated so that the module could be loaded on PPC64.

static int __init index_start(void)
{
         printk(KERN_INFO "Indexing service\n");

         return 0;
}

What do you think?

Regards,
