I'll see more carefully the code later. Probably long > time discontig-mem uninterest made multiple level breakage. Grr. ;-) True. Someone needs to go through discontig and make it work right with a !NUMA configuration. Many pieces of the core code assume that there will be no node on a !NUMA config today. I guess that was different in ages past. Maybe we should make DISCONTIG broken under !NUMA until that time? Tejon was working on getting rid of DISCONTIG. SPARSEMEM is the favored alternative today. So we could potentially change the arches to use SPARSE configs in the !NUMA case. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
