One thing that I would consider an improvement is to have a way to subscribe drivers with excessive memory consumption or those which are struggling to dump their state. Maybe your proposal can be extended that way but the crucial point is to not dump all sorts of random shrinkers' state and end up with unwieldy reports. If, on the other hand, any particular shrinker struggles to reclaim memory and it is sitting on a lot of memory it could be able to flag itself to be involved in the dump. -- Michal Hocko SUSE Labs
