This is in arma's commit f5ff9f23 in his bug24898-more branch. This comment is wrong, the check is already implemented in channel_add_to_digest_map(): ``` + /* XXX we might want to replace this logic with a call to + * channel_is_client() instead. Or maybe we can change + * channel_identity_mapso it refuses to add any channels that are + * client channels? */ ``` So we can remove the check entirely.
