Hello, It's seen that btrfs_mknod doesn't save device number in rdev field of inode. you can test the issue by: (1) create a device file with non-zero major and minor device number (2) umount the filesystem (3) mount the filesystem. after do the steps above, you can find both major and minor device number become zero.
