and now, courtesy of my handy-dandy dead CONFIG variable spotter, we have the first in a series of posts identifying CONFIG_ variables that don't appear to be set anywhere in the configuration process, along with a recursive grep showing where they're referenced.
as a first example, restricting the search to the mm/ directory: $ ../dead_config.sh mm ========== MAX_ACTIVE_REGIONS ========== mm/page_alloc.c: #ifdef CONFIG_MAX_ACTIVE_REGIONS mm/page_alloc.c: #define MAX_ACTIVE_REGIONS CONFIG_MAX_ACTIVE_REGIONS mm/page_alloc.c: * MAX_ACTIVE_REGIONS determines the maxmimum number of distinct mm/page_alloc.c: /* Allow an architecture to set MAX_ACTIVE_REGIONS to save memory */ mm/page_alloc.c: #define MAX_ACTIVE_REGIONS CONFIG_MAX_ACTIVE_REGIONS mm/page_alloc.c: #define MAX_ACTIVE_REGIONS (MAX_NUMNODES*50) mm/page_alloc.c: #define MAX_ACTIVE_REGIONS 256 mm/page_alloc.c: struct node_active_region __initdata early_node_map[MAX_ACTIVE_REGIONS]; mm/page_alloc.c: nr_nodemap_entries, MAX_ACTIVE_REGIONS); mm/page_alloc.c: if (i >= MAX_ACTIVE_REGIONS) { mm/page_alloc.c: MAX_ACTIVE_REGIONS); is it fair to say there's something strange going on here before i run any more tests? rday -- ======================================================================== Robert P.
