I wonder if I am subconsciously trying to break a record or 
something! My apologies as time is valuable. 

I mean to get this right. My rationale for using audit_info was to
reduce amount of arguments to xfrm_audit_log(). However, I now like
it better when I just called xfrm_audit_log(NETLINK_CB(skb).loginuid,
NETLINK_CB(skb).sid, ...). User determines where/how to get loginuid and
secid and nothing happens when AUDIT not configured. But would make
xfrm_audit_log() have 7 arguments instead of 6.

My alternative is to remove xfrm_get_auditinfo() out of the 
#ifdef CONFIG_AUDITSYSCALL and always fill in audit_info
regardless if AUDIT is configured or not. Less calls to
xfrm_audit_log() but perhaps unnecessary info when AUDIT 
not configured.

Would first solution be acceptable?
