Wow sometimes maintaining gearmand feels like working on an archeological dig.
Agree with your assessment. Remove that extra check. It might even get optimized out in some cases.
Anyway, I looked at some of the calls to this and funny enough the only one I could find that uses the argv's was my own addition of --round-robin mode.

This PR fixes an "issue" reported by the CodeQL scan of the gearmand source code. The null check on line 179 of libtest/server.cc is redundant because it has already been dereferenced on line 177 in the condition of the
forloop.I suppose the
if (argv) { ... }around theforloop could also be removed since the new condition of theforloop will also test this, but it doesn't do any harm and arguably improves clarity. I'd be willing to remove it though if you think it should be removed, @SpamapS.
