From f8403a2e47afb37bcd3b7e286996d138a116c39d Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Mon, 22 Dec 2014 18:56:36 +0100 Subject: [PATCH] genetlink: pass only network namespace to genl_has_listeners() There's no point to force the caller to know about the internal genl_sock to use inside struct net, just have them pass the network namespace. This doesn't really change code generation since it's an inline, but makes the caller less magic - there's never any reason to pass another socket.
