Hi, I'm wondering why kmem -f uses the spanned pages of every zone when reporting its size. Wouldn't it be more informative to get a value which excludes any holes? This is the code from memory.c I'm thinking of: /* * Same as dump_free_pages_zones_v1(), but updated for numerous 2.6 zone * and free_area related data structure changes. */ static void dump_free_pages_zones_v2(struct meminfo *fi) { [...] if (VALID_MEMBER(zone_spanned_pages)) zone_size_offset = OFFSET(zone_spanned_pages); else error(FATAL, "zone struct has no spanned_pages field\n"); [...] } Regards, Per
