The following CI failures came up: 1. laio_has_fua() is missing on some host OSes: https://gitlab.com/qemu-project/qemu/-/jobs/9380928997#L3369 2. io_uring_prep_writev2() without #ifdef HAVE_IO_PREP_PWRITEV2: https://gitlab.com/qemu-project/qemu/-/jobs/9380928883#L2515 3. qemu-iotests 051: https://gitlab.com/qemu-project/qemu/-/jobs/9380928853#L4519 Please send a v2 pull request.
