So I hope you realize that high order allocation is no free lunch. __GFP_NORETRY makes no sense really. Even though we have compaction, high order reclaim is still costly operation. I don't think SLUB's high order allocation trying is bad idea. but now It does more costly trying. that's bad. Also I'm worry about SLUB assume too higher end machine. Now Both SLES and RHEL decided to don't use SLUB, instead use SLAB. Now linux community is fragmented. If you are still interesting SL*B unification, can you please consider to join corner case smashing activity? -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxxx For more info on Linux MM, see: http://www.linux-mm.org/ .
