FIND_NEXT_BEST_NODE(9)					    Memory Management in Linux					    FIND_NEXT_BEST_NODE(9)

NAME
       find_next_best_node - find the next node that should appear in a given node's fallback list

SYNOPSIS
       int find_next_best_node(int node, nodemask_t * used_node_mask);

ARGUMENTS
       node
	   node whose fallback list we're appending

       used_node_mask
	   nodemask_t of already used nodes

DESCRIPTION
       We use a number of factors to determine which is the next node that should appear on a given node's fallback list. The node should not have
       appeared already in node's fallback list, and it should be the next closest node according to the distance array (which contains arbitrary
       distance values from each node to each node in the system), and should also prefer nodes with no CPUs, since presumably they'll have very
       little allocation pressure on them otherwise. It returns -1 if no node is found.
