    afs: Deal with an empty callback array · bcd89270
    Marc Dionne 提交于
    Servers may send a callback array that is the same size as
    the FID array, or an empty array.  If the callback count is
    0, the code would attempt to read (fid_count * 12) bytes of
    data, which would fail and result in an unmarshalling error.
    This would lead to stale data for remotely modified files
    or directories.
    
    Store the callback array size in the internal afs_call
    structure and use that to determine the amount of data to
    read.
