    [PATCH] map multiple blocks for mpage_readpages() · fa30bd05
    Badari Pulavarty 提交于
    This patch changes mpage_readpages() and get_block() to get the disk mapping
    information for multiple blocks at the same time.
    
    b_size represents the amount of disk mapping that needs to mapped.  On the
    successful get_block() b_size indicates the amount of disk mapping thats
    actually mapped.  Only the filesystems who care to use this information and
    provide multiple disk blocks at a time can choose to do so.
    
    No changes are needed for the filesystems who wants to ignore this.
