From 7f6856b789ff13ccfd317c936e4b161c0bbd88a3 Mon Sep 17 00:00:00 2001 From: Kees Cook Date: Fri, 16 Dec 2016 17:05:42 -0800 Subject: [PATCH] RDMA/i40iw: use designated initializers Prepare to mark sensitive kernel structures for randomization by making sure they're using designated initializers. These were identified during allyesconfig builds of x86, arm, and arm64, with most initializer fixes extracted from grsecurity.
