    [PATCH] remove /proc/sys/vm/dirty_sync_thresh · da1eca60
    Andrew Morton authored
    This was designed to be a really sterm throttling threshold: if dirty
    memory reaches this level then perform writeback and actually wait on
    it.
    
    It doesn't work.  Because memory dirtiers are required to perform
    writeback if the amount of dirty AND writeback memory exceeds
    dirty_async_ratio.
    
    So kill it, and rely just on the request queues being appropriately
    scaled to the machine size (they are).
    
    This is basically what 2.4 does.
