    [PATCH] page accounting · d878155c
    Andrew Morton authored
    This patch provides global accounting of locked and dirty pages.  It
    does this via lightweight per-CPU data structures.  The page_cache_size
    accounting has been changed to use this facility as well.
    
    Locked and dirty page accounting is needed for making writeback and
    throttling decisions.
    
    The patch also starts to move code which is related to page->flags
    out of linux/mm.h and into linux/page-flags.h
