    [PATCH] Turn do_sync_file_range() into do_sync_mapping_range()
    
    do_sync_file_range() accepts a file * from which it takes an address_space 
to
    sync.  Abstract out the bulk of the function into do_sync_mapping_range()
    which takes the address_space directly.  This way callers who want to sync 
an
    address_space directly can take advantage of the functionality provided.
    
    do_sync_file_range() is preserved as a small wrapper around
    do_sync_mapping_range().
    
    Ocfs2 in particular would like to use this to initiate a sync of a specific
    inode range during truncate, where a file * may not be available.
