Message from Gopher Robot:

Patch Set 1:

Congratulations on opening your first change. Thank you for your contribution!

Next steps:
A maintainer will review your change and provide feedback. See
https://go.dev/doc/contribute#review for more info and tips to get your
patch through code review.

Most changes in the Go project go through a few rounds of revision. This can be
surprising to people new to the project. The careful, iterative review process
is our way of helping mentor contributors and ensuring that their contributions
have a lasting impact.

During May-July and Nov-Jan the Go project is in a code freeze, during which
little code gets reviewed or merged. If a reviewer responds with a comment like
R=go1.11 or adds a tag like "wait-release", it means that this CL will be
reviewed as part of the next development cycle. See https://go.dev/s/release
for more details.

I don't quite understand what is the correct fix

In the comments for the 1.17 branch,go:linkname must refer to declared function or variable will become an error in version 1.17, but in fact, version 1.18 only throws it as an error

@bcmills cound you take a look when you have time

Thanks for your interest in helping, but this CL is unnecessary. We don't care about internal comments in obsolete versions of Go.
