+
+Kconfig Parameters:
+
+CONFIG_DEBUG_LOCK_ALLOC -- Do all three and none of the three.
+CONFIG_PREEMPT_COUNT
+CONFIG_RCU_TRACE
+
+The theory here is that randconfig testing will hit the other six possible
+combinations of these parameters.
+
+
+Kconfig Parameters Ignored:
+
+CONFIG_DEBUG_OBJECTS_RCU_HEAD
+CONFIG_PROVE_RCU
+
+ In common code tested by TREE_RCU test cases.
+
+CONFIG_NO_HZ_FULL_SYSIDLE
+CONFIG_RCU_NOCB_CPU
+CONFIG_RCU_USER_QS
+
+ Meaningless for TINY_RCU.
+
+CONFIG_RCU_STALL_COMMON
+CONFIG_RCU_TORTURE_TEST
+
+ Redundant with CONFIG_RCU_TRACE.

+CONFIG_PREEMPT_RCU
+CONFIG_SMP

+
+
+Kconfig Parameters Ignored:
+
+CONFIG_64BIT
+
+ Used only to check CONFIG_RCU_FANOUT value, inspection suffices.

+CONFIG_NO_HZ_FULL_SYSIDLE_SMALL
+
+ Defer until Frederic uses this.
+
+CONFIG_PREEMPT_COUNT
+CONFIG_PREEMPT_RCU
+
+ Redundant with CONFIG_PREEMPT, ignore.
+
+CONFIG_RCU_BOOST_DELAY
+
+ Inspection suffices, ignore.
+
+CONFIG_RCU_CPU_STALL_TIMEOUT
+
+ Inspection suffices, ignore.
+
+CONFIG_RCU_STALL_COMMON
+
+ Implied by TREE_RCU and TREE_PREEMPT_RCU.
+
+CONFIG_RCU_TORTURE_TEST
+CONFIG_RCU_TORTURE_TEST_RUNNABLE
+
+ Always used in KVM testing.
+
+CONFIG_RCU_USER_QS
+
+ Redundant with CONFIG_NO_HZ_FULL.
+
+CONFIG_TREE_PREEMPT_RCU

+This document describes one way to create the initrd directory hierarchy
+in order to allow an initrd to be built into your kernel. The trick
+here is to steal the initrd file used on your Linux laptop, Ubuntu in
+this case. There are probably much better ways of doing this.
+
+That said, here are the commands:
+
+------------------------------------------------------------------------
+zcat /initrd.img > /tmp/initrd.img.zcat
+mkdir initrd
+cd initrd
+cpio -id < /tmp/initrd.img.zcat
+------------------------------------------------------------------------
+
+Interestingly enough, if you are running rcutorture, you don't really
+need userspace in many cases. Running without userspace has the
+advantage of allowing you to test your kernel independently of the
+distro in place, the root-filesystem layout, and so on. To make this
+happen, put the following script in the initrd's tree's "/init" file,
+with 0755 mode.
+
+------------------------------------------------------------------------
+#!/bin/sh
+
+[ -d /dev ] || mkdir -m 0755 /dev
+[ -d /root ] || mkdir -m 0700 /root
+[ -d /sys ] || mkdir /sys
+[ -d /proc ] || mkdir /proc

+# Some things don't work properly without /etc/mtab.
+ln -sf /proc/mounts /etc/mtab
+
+# Note that this only becomes /dev on the real filesystem if udev's scripts
+# are used; which they will be, but it's worth pointing out
+if ! mount -t devtmpfs -o mode=0755 udev /dev; then
+ echo "W: devtmpfs not available, falling back to tmpfs for /dev"

+This document describes one way to created the rcu-test-image file
