Just be aware that putting a comment along with the reviewed-by tag
is always a good idea.  I know that's a little more work, but this has
been raised a number of times by various people over the years.

A reviewed-by tag on its own doesn't mean much, as it could mean that
you've just glanced over the code and decided "yea, it looks okay", or
it could mean that you've spent all day verifying that the code change
is indeed correct.

Consequently, some will ignore emails which just contain a reviewed-by
attributation.
