I do not think that the page allocator would blow up even with GFP_THISNODE. The allocation would just fail on memory less node. Besides that kmalloc_node shouldn't really have an implicit GFP_THISNODE semantic right? At least I do not see anything like that documented anywhere. -- Michal Hocko SUSE Labs
