From 5eb7c0d04f04a667c049fe090a95494a8de2955c Mon Sep 17 00:00:00 2001 From: Larry Finger Date: Sun, 1 Jan 2017 20:25:25 -0600 Subject: [PATCH] taint/module: Fix problems when out-of-kernel driver defines true or false Commit 7fd8329ba502 ("taint/module: Clean up global and module taint flags handling") used the key words true and false as character members of a new struct. These names cause problems when out-of-kernel modules such as VirtualBox include their own definitions of true and false.
