The write pattern value 0axb is invalid and evaluates to 0, so the read check (which uses a correct value of 0xab) will fail. This failure will only be detected with a separate patch for qemu-io. Without it, qemu-io cannot interpret hex values and always uses a pattern value of 0. Signed-off-by: Stefan Weil <weil@mail.berlios.de> Signed-off-by: Christoph Hellwig <hch@lst.de>
