Yeah I remember it was 0day report but I coundn't find it in my email
archive. Do you happen to have a message-id?
Anyway
if (__ratelimit(&oom_rs))
dump_header(oc, p);
+ if (oc)
+ dump_oom_summary(oc, victim);
Clearly cannot solve any NULL ptr because oc is never NULL unless I am
missing something terribly.
