commit 0fdf977d4576ee0decd612e22f6a837a239573cc upstream.
When a bio is split in btrfs_submit_direct, dip->file_offset contains the file offset for the first bio. But this means the start value used in btrfs_end_dio_bio to record the write location for zone devices is incorrect for subsequent bios.
