[Qemu-block] [PATCH 0/6] block: Enable byte granularity I/O |

Previous series have already converted some block drivers to byte-based rather
than sector-based interfaces. However, the common I/O path as well as raw-posix
still enforced a minimum alignment of 512 bytes because some sector-based logic
was involved.
This patch series removes these limitations and a sub-sector request actually
ends up as a sub-sector syscall now.
Kevin Wolf (6):
block: Byte-based bdrv_co_do_copy_on_readv()
block: Prepare bdrv_aligned_preadv() for byte-aligned requests
block: Prepare bdrv_aligned_pwritev() for byte-aligned requests
raw-posix: Switch to bdrv_co_* interfaces
raw-posix: Implement .bdrv_co_preadv/pwritev
block: Don't enforce 512 byte minimum alignment
