[Qemu-devel] [PATCH 0/5] qcow2: Implement .bdrv_co_preadv/pwritev

[Kevin Wolf]

This series converts qcow2 to the byte-based I/O interfaces. This simplifies
the code by removing many unit conversions, and in the unlikely case of actual
unaligned requests, it even makes the driver work more efficiently by avoiding
read-modify-write.

Kevin Wolf (5):
  qcow2: Work with bytes in qcow2_get_cluster_offset()
  qcow2: Implement .bdrv_co_preadv()
  qcow2: Make copy_sectors() byte based
  qcow2: Use bytes instead of sectors for QCowL2Meta
  qcow2: Implement .bdrv_co_pwritev
