From 702e490211b2b7e448ebe1b3a07d97ad2fc07e03 Mon Sep 17 00:00:00 2001 From: "Eric W. Biederman" Date: Tue, 2 Oct 2012 15:37:37 -0700 Subject: userns: Fix build of drivers/staging/dgrp Explicitly test for GLOBAL_ROOT_UID and GLOBAL_ROOT_GID instead of using 0, allowing dgrp to compile and work properly when user namespace support is enabled.
