    Subjectata_sff_data_xfer* return value
    Date
    Hi,

    I wonder if this is entirely correct? If so, why?
    Only relevant parts left.

    * RETURNS:
    * Bytes consumed.
    ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
    */
    unsigned int ata_sff_data_xfer(struct ata_device *dev, unsigned char *buf,
    unsigned int buflen, int rw)
    {
    unsigned int words = buflen >> 1;

    ...

    /* Transfer trailing byte, if any. */
    if (unlikely(buflen & 0x01)) {
    ...
    words++;
    }

    return words << 1;



    same here:

    unsigned int ata_sff_data_xfer32(struct ata_device *dev, unsigned char *buf,
    unsigned int buflen, int rw)
    {
    ...
    return (buflen + 1) & ~1;

    Please keep me in CC:, I'm not on the IDE list. Thanks.
