Some names in MM really make people confused. But sometimes thinking
an appropriate name is also a hard thing. Like I once wanted to change
the name of function nr_free_zone_pages() and also nr_free_buffer_pages().
But it is hard to name them, so at last Andrew suggested to add the
detailed function description to make it clear only.
