    If you pursued it, wouldn't your patch also need to change
    nr_free_buffer_pages() to do what you think it does, count
    the free lowmem pages? It, and nr_free_pagecache_pages(),
    and nr_free_zone_pages(), are horribly badly named. They
    count present_pages-pages_high, they don't count free pages:
    okay for initialization estimates, useless for anything dynamic.


    p.s. any chance of some more imaginative Subject lines :-?
