Yeah, that are the handles and not the entries. Sorry that I was
confused about that.
Your patch is correct, you should just update the commit message a bit.
BTW: Could you cleanup error handling here a bit more?
E.g. add an error_put_list handle and drop the "if (info)" and instead
return directly if we fail to allocate info.
Thanks,
Christian.
