2.6.21 fix lba48 bug in libata fill_result_tf()
Current 2.6.21 libata does the following: void ata_tf_read(struct ata_port *ap, struct ata_taskfile *tf) { struct ata_ioports *ioaddr = &ap->ioaddr; tf->command = ata_check_status(ap); ... if (tf->flags & ATA_TFLAG_LBA48) { iowrite8(tf->ctl | ATA_HOB, ioaddr->ctl_addr); tf->hob_feature = ioread8(ioaddr->error_addr); ... } } ... static void fill_result_tf(struct ata_queued_cmd *qc) { struct ata_port *ap = qc->ap; ap->ops->tf_read(ap, &qc->result_tf); qc->result_tf.flags = qc->tf.flags; } Based on this, those last two statements fill_result_tf() appear to me to be in the wrong order, in that the tf->flags are uninitialized at the point where tf_read() is invoked. So for lba48 commands, tf_read() won't be reading back the full lba48 register contents.. Correct? This patch corrects fill_result_tf() so that the flags get copied to result_tf before they are used by tf_read().
