Hi Manish,

Good catch, I ran compile tests with different SECURITY/NETLABEL/IPV6 
options enabled/disabled but forgot about AUDIT.  I appreciate your 
help finding this and submitting a possible solution but I think the 
better approach would be to conditionally compile out the 
netlbl_af{4,6}list_audit_addr() functions similarly to what we do with 
several of the NetLabel kernel API functions in include/net/netlabel.h, 
see netlbl_enabled() for a simple example.

If you have the time to revise this patch that would be great, just CC 
me on the posting and I'll look it over.  If you don't have time that 
is okay too, just let me know so I can fix it.

Thanks!
