I'm not sure that sharing subscriber's link to such a wide audience like Hacker News is really ok. LWN doesn't limit you in the sharing, but some common sense should restrain you from abusing this privilege.

The submitter there is "corbet", that is, Jonathan Corbet, the guy who runs LWN.
So it's probably fine.
