I will do it.

it seems "it is not suitable to send any issues which only relative
with Red Hat to linux-*@vger.kernel.org".

1) I agree with your result.

2) But for the "reason", I have my opinions:
A) %.8s : for limitation of output string length.
B) %8s : for width of output string length (but not limit 8).
C) %8.8s: both limitation and width.

3) for rt->rt6i_dev->name:
A) original %8s is not a bug for name len is more than 8 (can still
be outputted correctly)
B) it is only effect with name len is less than 8 (it will fill some
' ' before the name)
C) this is the reason why I call it "beautiful", not a bug.
