I had to rebase the series due to conflicting changes on master. There
are no other differences.

Berto

v4:
- Fix rebase conflicts after cb8503159a

v3: https://lists.gnu.org/archive/html/qemu-block/2020-09/msg00912.html
- Add a new patch to improve the reporting of BDRV_BLOCK_ZERO [Vladimir]
- Rename function to bdrv_co_is_zero_fast() [Vladimir, Kevin]
- Don't call bdrv_common_block_status_above() if bytes == 0

v2: https://lists.gnu.org/archive/html/qemu-block/2020-08/msg01165.html
- Add new, simpler API: bdrv_is_unallocated_or_zero_above()

v1: https://lists.gnu.org/archive/html/qemu-block/2020-08/msg00403.html

Alberto Garcia (2):
  qcow2: Report BDRV_BLOCK_ZERO more accurately in
    bdrv_co_block_status()
  qcow2: Skip copy-on-write when allocating a zero cluster
