From 377e7a27c049d6df9c1804454904e438ed12f1a4 Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Sun, 11 Dec 2016 18:00:43 +0100 Subject: Make static usermode helper binaries constant There are a number of usermode helper binaries that are "hard coded" in the kernel today, so mark them as "const" to make it harder for someone to change where the variables point to.
