What you seem to ignore is that whatever method you use for reporting stalling allocations you would still have to consider whether to dump a stall information for __GFP_NOWARN ones. And as the current report shows that might be a bad idea. So please stick to the topic and do not move it towards _what_ is the proper way of stall detection. -- Michal Hocko SUSE Labs -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
