Date: Mon, 28 Sep 2020 17:57:18 -0700 From: Jakub Kicinski <kuba@...nel.org> To: davem@...emloft.net Cc: mkubecek@...e.cz, netdev@...r.kernel.org, Jakub Kicinski <kuba@...nel.org> Subject: [PATCH net] ethtool: mark netlink policy as __ro_after_init 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.
