[LTP] [PATCH v1 1/1] keyctl05: improve the dns_res_payload for boundary testing

Hi Xu,

I'm sorry, I was faster and just fixed \ myself.
Rebasing is trivial, but there was missing commit (already merged and other
things). Thus I have sent v2 under your name (which I actually forget to mark
as v2 :().

Can you please have a look on it?

Kind regards,
Petr
