PSA: intent to sunset the kernel-testers list

Hello:

We are in the process of migrating vger lists to new infrastructure. The
kernel-testers list has been largely inactive for the past 8 years, so the
current plan is to:

- close the list
- set up an auto-responder stating that the list is closed
- include a link in the auto-responder message that points to the list
  archives at https://lore.kernel.org/kernel-testers/

Please speak up if you have any objections to this plan.
