I do not remember complaining about anything unacceptable for this patch. I just thought it was way too large the last time I have looked at it. Johannes was suggesting to simply extend warn_alloc_failed to also report too many retries with some extended information as a more lightweight approach. It wouldn't give as much information as your watchdog but maybe it would be sufficient to figure out that something really bad is going on. Dunno but I would rather see a more lightweight debugging aid than a lot of code which sit basically unused most of the time. That being said I cannot comment on this particular version as I haven't checked it properly yet. -- Michal Hocko SUSE Labs -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
