  Reviewer guidance
  -----------------

  Reviewing other people's patches on the list is highly encouraged,
  regardless of the level of expertise. For general guidance and
  helpful tips please see :ref:`development_advancedtopics_reviews`.

  It's safe to assume that netdev maintainers know the community and
  the level of expertise of the reviewers. The reviewers should not be
  concerned about their comments impeding or derailing the patch flow.

  Less experienced reviewers are highly encouraged to do more in-depth
  review of submissions and not focus exclusively on trivial or
  subjective matters like code formatting, tags etc.
