[Btrfs-devel] btrfs_mknod doesn't save device number.

[Yan Zheng]

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.
