This kernel Oopses immediately on boot. I think its the string1 & string2 patches. Here's what I get:

Then with gdb, I find this line:

(gdb) list *0xffffffff801614c4
0xffffffff801614c4 is in audit_receive_filter (kernel/auditfilter.c:388).
383                     audit_free_watch(krule->watch);
384                     krule->watch = w;
385                     list_add(&krule->rlist, &w->rules);
386                     return;
387             }
388             INIT_LIST_HEAD(&krule->watch->rules);
389             list_add(&krule->rlist, &krule->watch->rules);
390             list_add(&krule->watch->mlist, &master_watchlist);
391     }

So, seems that krule is NULL?
