Name:Build zonelists ordered by zone and nodes within zones.* This results in conserving DMA zone[s] until all Normal memory is* exhausted, but results in overflowing to remote node while memory* may still exist in local DMA zone.
Proto:static void build_zonelists(pg_data_t *pgdat)
Type:void
Parameter:
Type | Parameter | Name |
---|---|---|
pg_data_t * | pgdat |
5611 | nr_nodes = 0 |
5616 | local_node = node_id |
5617 | load = nr_online_nodes |
5618 | prev_node = local_node |
5619 | nodes_clear(used_mask) |
5621 | memset(node_order, 0, size of node_order ) |
5628 | If node_distance(local_node, node) != node_distance(local_node, prev_node) Then node_load[node] = load |
