I'd hate having to special case them even more. Especially as the discard splitting is nasty and we really don't want to send giant discards by default anyway (see Jens' patches to limit discard size by default). So I'd recommend to keep everything as-is, just make sure we don't overflow bi_size. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
