    the logical file blocks.
    
    This is the preparatory patch to support large files in ext4
    The follow up patch with convert the ext4_inode i_blocks to
    represent the number of blocks in file system block size. This
    changes makes it possible to have a block number 2**32 -1 which
    will result in overflow if the block number is represented by
    signed long. This patch convert all the block number to type
    ext4_lblk_t which is typedef to __u32
