Thanks Roland for your reply. Could please clarify my doubt.

When we need to add a probe point to kernel, we check for  relocation
information for it, through dwfl_module_relocations().
For a kernel which is built without CONFIG_RELOC option,there will be 
no relocation info. Hence I expect dwfl_module_relocations() to return 0.
(Please correct If Iam wrong)

But In my system with elfutils-0.131, Iam getting return value of 
dwfl_module_relocations() as 1.(Thats because mod->e_type is ET_DYN)
I think thats a wrong value. This is causing some bugs in systemtap.

Could please throw some light on this.

Thanks
