    [PATCH] show_free_areas() cleanup · c1ab3459
    Andrew Morton authored
    Cleanup to show_free_areas() from Bill Irwin:
    
    show_free_areas() and show_free_areas_core() is a mess.
    (1) it uses a bizarre and ugly form of list iteration to walk buddy lists
            use standard list functions instead
    (2) it prints the same information repeatedly once per-node
            rationalize the braindamaged iteration logic
    (3) show_free_areas_node() is useless and not called anywhere
            remove it entirely
    (4) show_free_areas() itself just calls show_free_areas_core()
            remove show_free_areas_core() and do the stuff directly
    (5) SWAP_CACHE_INFO is always #defined, remove it
    (6) INC_CACHE_INFO() doesn't use the do { } while (0) construct
    
    This patch also includes Matthew Dobson's patch which removes
    mm/numa.c:node_lock.  The consensus is that it doesn't do anything now
    that show_free_areas_node() isn't there.
