    [SCSI] introduce shost_priv helper · bcd92c9f
    Christoph Hellwig 提交于
    Currently accessing the scsi host private data is rather messy because
    it comes as an unsigned long that always needs a cast first.  This patch
    introduces a helper that does the cast called shost_priv.  It's similar
    in spirit to netdev_priv for network drivers.
    
    This is the first patch introducing the macro, and the second patch
    in the series will convert esp and it's subdrivers as an example.
    Further conversion will wait until the helper is in the tree to make
    patch juggling easier.
