    Christoph Hellwig authored
    Add support for larger btree blocks that contains a CRC32C checksum,
    a filesystem uuid and block number for detecting filesystem
    consistency and out of place writes.
    
    [dchinner@redhat.com] Also include an owner field to allow reverse
    mappings to be implemented for improved repairability and a LSN
    field to so that log recovery can easily determine the last
    modification that made it to disk for each buffer.
    
    [dchinner@redhat.com] Add buffer log format flags to indicate the
    type of buffer to recovery so that we don't have to do blind magic
    number tests to determine what the buffer is.
    
    [dchinner@redhat.com] Modified to fit into the verifier structure.
