Subject: Re: [PATCH net v2] ethtool: mark netlink family as __ro_after_init

From: Jakub Kicinski <>
Date: Mon, 28 Sep 2020 17:58:41 -0700

> Like all genl families ethtool_genl_family needs to not
> be a straight up constant, because it's modified/initialized
> by genl_register_family(). After init, however, it's only
> passed to genlmsg_put() & co. therefore we can mark it
> as __ro_after_init.
> Since genl_family structure contains function pointers
> mark this as a fix.
