The following two errors occur when mkfs.btrfs is called on a regular file
with emulated zones. These patches address the errors.

ERROR: zoned: failed to read size of /home/naota/tmp/btrfs.img: Inappropriate ioctl for device

ERROR: zoned: failed to reset device '/home/naota/tmp/btrfs.img' zones: Inappropriate ioctl for device

Naohiro Aota (2):
  btrfs-progs: use btrfs_device_size() instead of
    device_get_partition_size_fd()
  btrfs-progs: do not zone reset on emulated zoned mode

Added to devel, thanks.
