From: Kees Cook Date: Wed, 29 Mar 2017 21:02:19 +0000 (-0700) Subject: ovl: Use designated initializers X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=33006cdf9c038dca9b3d4c148a509de851a66ea9;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git ovl: 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. For these cases, use { }, which will be zero-filled, instead of undesignated NULLs.
