From 9bfc7b9969dbb800460e2577f1dea59336269ce4 Mon Sep 17 00:00:00 2001 From: Alexey Dobriyan Date: Fri, 2 Dec 2016 04:12:58 +0300 Subject: netns: add dummy struct inside "struct net_generic" This is precursor to fixing "[id - 1]" bloat inside net_generic(). Name "s" is chosen to complement name "u" often used for dummy unions. Signed-off-by: Alexey Dobriyan Signed-off-by: David S.
