([PATCH v7 00/10] qemu-img convert with copy offloading)

This enhances the backup job to make use of the copy offloading API. It
eliminates the necessity to use the bounce buffer as well as speeding up the
copy operation when the backend supports it.

v3: Don't forget coroutine_fn. [Stefan]
    Don't reset job->use_copy_range redundantly. [Stefan]

v2: Use helper functions. [Stefan]

Fam Zheng (2):
  block: Honour BDRV_REQ_NO_SERIALISING in copy range
  backup: Use copy offloading
