Perhaps a naive question - why dont we have BUCKET_MAX beyond 128? I would think that allocating a full page for buckets would be more efficient and also reduce the number of bucket allocations needed for other UMA zones. On a related note is there a reason why zone_clust does not use UMA_ZONE_MAXBUCKET? Any objections in adding this flag to zone_clust? -vijay
