Ok, so we got a useless pglist_data struct and the struct zone contains a zonelist that does not include the zone. numa_node_id() points to this and we always get allocations redirected to other nodes. The slab duplicates its per node structures on the fallback node. > The zonelist[] donen't contain empty-zone. So we will never encounter that zone except when going to the pglist_data struct through numa_node_id()? - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
