From 871480933a1c28f8a9fed4c4d34d06c439a7a422 Mon Sep 17 00:00:00 2001 From: Srikant Patnaik Date: Sun, 11 Jan 2015 12:28:04 +0530 Subject: Moved, renamed, and deleted files The original directory structure was scattered and unorganized. Changes are basically to make it look like kernel structure. --- ANDROID_3.4.5/include/linux/lguest_launcher.h | 73 --------------------------- 1 file changed, 73 deletions(-) delete mode 100644 ANDROID_3.4.5/include/linux/lguest_launcher.h (limited to 'ANDROID_3.4.5/include/linux/lguest_launcher.h') diff --git a/ANDROID_3.4.5/include/linux/lguest_launcher.h b/ANDROID_3.4.5/include/linux/lguest_launcher.h deleted file mode 100644 index 495203ff..00000000 --- a/ANDROID_3.4.5/include/linux/lguest_launcher.h +++ /dev/null @@ -1,73 +0,0 @@ -#ifndef _LINUX_LGUEST_LAUNCHER -#define _LINUX_LGUEST_LAUNCHER -/* Everything the "lguest" userspace program needs to know. */ -#include - -/*D:010 - * Drivers - * - * The Guest needs devices to do anything useful.
