From: Yousong Zhou Date: Wed, 11 Jan 2017 11:57:24 +0000 (+0800) Subject: generic: keep module aliases inside .modinfo X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=d5de9264bb5b9e825d3679fddf9ad2564a046b49;p=openwrt%2Fstaging%2Fthess.git generic: keep module aliases inside .modinfo It seems module aliases are actually essential info. E.g. other modules may call xt_request_find_match(NFPROTO_IPV{4,6}, "hashlimit", 1) and the kernel will request user mode modprobe helper for ipt_hashlimit and ip6t_hashlimit respectively which are aliases of xt_hashlimit.ko Compile-tested for armvirt, there is nearly no size impact.
