do_rw_taskfile() is going to be used by fs requests once __ide_do_rw_disk() is converted to taskfile transport. I don't think that do_rw_taskfile() and flagged_taskfile() merge is a good thing as it adds unnecessary overhead for hot path (fs requests). - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
