rcutorture: Add KVM-based test framework

1This document describes one way to create the initrd directory hierarchy
2in order to allow an initrd to be built into your kernel. The trick
3here is to steal the initrd file used on your Linux laptop, Ubuntu in
4this case. There are probably much better ways of doing this.
5
6That said, here are the commands:
7
8------------------------------------------------------------------------
9zcat /initrd.img > /tmp/initrd.img.zcat
10mkdir initrd
11cd initrd
12cpio -id < /tmp/initrd.img.zcat
13------------------------------------------------------------------------
14
15Interestingly enough, if you are running rcutorture, you don't really
16need userspace in many cases. Running without userspace has the
17advantage of allowing you to test your kernel independently of the
18distro in place, the root-filesystem layout, and so on. To make this
19happen, put the following script in the initrd's tree's "/init" file,
20with 0755 mode.
21
22------------------------------------------------------------------------
23#!/bin/sh
24
25[ -d /dev ] || mkdir -m 0755 /dev

34ln -sf /proc/mounts /etc/mtab

37# are used; which they will be, but it's worth pointing out
38if ! mount -t devtmpfs -o mode=0755 udev /dev; then
39 echo "W: devtmpfs not available, falling back to tmpfs for /dev"

1This document describes one way to created the rcu-test-image file
2that contains the filesystem used by the guest-OS kernel. There are
