    xfs: vectorise encoding/decoding directory headers · 01ba43b8
    Dave Chinner authored
    Conversion from on-disk structures to in-core header structures
    currently relies on magic number checks. If the magic number is
    wrong, but one of the supported values, we do the wrong thing with
    the encode/decode operation. Split these functions so that there are
    discrete operations for the specific directory format we are
    handling.
    
    In doing this, move all the header encode/decode functions to
    xfs_da_format.c as they are directly manipulating the on-disk
    format. It should be noted that all the growth in binary size is
    from xfs_da_format.c - the rest of the code actaully shrinks.
