Hi Peter,

Thanks for you review and tell us the better way to get relocation offset.

We no need care modules symbols since we get module load address from
'/proc/modules', no matter is relocated or not. And perf tools just use
this way. So, it done nothing about it in my patch, maybe i should mention
it in my patch's changlog

Thanks,
Xiao
