This is misleading. The "Link:" tag should point to the mail
where the commited version of the patch was being discussed.
It can be added by the maintainer.

Also please do not use links to https://lkml.org.
Messages disappear from time to time. It is much better
to use the redirector:

      https://lkml.kernel.org/r/<message_id>

Best Regards,
Petr

PS: I was about to add Reviewed-by tag. But Miroslav (sitting
next to me) found out that __noclone was not the best solution.

I suggest to always wait few days between re-sending a new
version. This subsystem has many active reviewers ;-)
