How to list all available reviews for coder? I am using drush with Coder (7.x-2.x) and I would like to know what are available options for reviews:

$ drush help coder
...
--reviews Run the specified review(s), "all" runs all reviews, also accepts a comma separated list (no spaces). 


Where I can find them?
The list will depend on which modules you have that implemented hook_reviews(); hook implementations return a keyed array that has the name of the review. These items are combined with a default list that come from the coder_review module.
The default list come from that dir is: upgrade47,   upgrade5x, upgrade6x, upgrade7x, upgrade8x, comment, druplart, i18n, i18n_po, production, security, sniffer, sql, style
