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. -- Krzysztof Halasa
