OK, we are mixing two things here. I was talking about alloc_ila_locks which is an init code AFAIU. If you are talking about alloc_bucket_locks then I would argue that the current code doesn't work as expected as the rehash happens from a kernel worker context and so the numa policy is out of control. I will reply to this email with the patches I have pending here and plan to post just to make sure we are at the same page. -- Michal Hocko SUSE Labs -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
