[ANNOUNCE] Email reviews from Sashiko enabled for kvm@

[Sean Christopherson <seanjc@google.com>]

FYI, we've opted-in kvm@vger.kernel.org for email reviews from Sashiko[*], so
don't be surprised if/when you start getting review feedback.  Given the broad
usage of kvm@, Sashiko is configured to email the patch author and Cc kvm@,
e.g. won't blast an email to the entire Cc of the original patch.

If Sashiko points out a real flaw, you'll likely get asked to address the issue,
but unless the maintainer(s) for a (sub)subsystem say otherwise, there are no
expectations that you respond to sashiko-bot (though it's totally fine and even
encouraged to do so).  In short, treat Sashiko like any other bot.

The signal:noise ratio for Sashiko has gotten pretty solid, so we don't expect
an onslaught of slop, but if there are problems with the volume and/or quality
of feedback, we'll adjust and tweak as needed (again, as we do for any other bot).

Thanks!
