    [PATCH] VM: add __GFP_NORECLAIM · 0c35bbad
    Martin Hicks authored
    When using the early zone reclaim, it was noticed that allocating new pages
    that should be spread across the whole system caused eviction of local pages.
    
    This adds a new GFP flag to prevent early reclaim from happening during
    certain allocation attempts.  The example that is implemented here is for page
    cache pages.  We want page cache pages to be spread across the whole system,
    and we don't want page cache pages to evict other pages to get local memory.
