   8 # space with a range (offset + length) that was not aligned with the block
   9 # size. This caused the btrfs receive command to send such clone operations
  10 # to the ioctl clone API, which would return -EINVAL errors to btrfs receive,
  11 # causing the receive command to abort immediately.
