Hugh Dickins ef53d16cde ksm: allocate roots when needed ... It is a pity to have MAX_NUMNODES+MAX_NUMNODES tree roots statically allocated, particularly when very few users will ever actually tune merge_across_nodes 0 to use more than 1+1 of those trees. Not a big deal (only 16kB wasted on each machine with CONFIG_MAXSMP), but a pity. Start off with 1+1 statically allocated, then if merge_across_nodes is ever tuned, allocate for nr_node_ids+nr_node_ids. Do not attempt to free up the extra if it's tuned back, that would be a waste of effort.
