From a7855c78a24d6348e989bec616318e68c662e78b Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Thu, 23 Sep 2010 23:51:51 +0000 Subject: net: loopback driver cleanup loopback driver uses dev->ml_priv to store its percpu stats pointer. It uses ugly casts "(void __percpu __force *)" to shut up sparse complains. Define an union to better document we use ml_priv in loopback driver and define a lstats field with appropriate types.
