Shutemov" , Mel Gorman , Michal Hocko , Vlastimil Babka It would be useful to translate gfp_flags into string representation when printing in case of an allocation failure, especially as the flags have been undergoing some changes recently and the script ./scripts/gfp-translate needs a matching source version to be accurate.
