    libata: update ->data_xfer hook for ATAPI · 55dba312
    Tejun Heo authored
    Depending on how many bytes are transferred as a unit, PIO data
    transfer may consume more bytes than requested.  Knowing how much
    data is consumed is necessary to determine how much is left for
    draining.  This patch update ->data_xfer such that it returns the
    number of consumed bytes.
    
    While at it, it also makes the following changes.
    
    * s/adev/dev/
    * use READ/WRITE constants for rw indication
    * misc clean ups
