+not listed here.  To reduce OS jitter from non-per-CPU kthreads, bind
+them to a "housekeeping" CPU dedicated to such work.

+KTHREADS
+
+Name: ehca_comp/%u
+Purpose: Periodically process Infiniband-related work.
+To reduce its OS jitter, do any of the following:
+1.      Don't use eHCA Infiniband hardware, instead choosing hardware
+        that does not require per-CPU kthreads.  This will prevent these
+        kthreads from being created in the first place.  (This will
+        work for most people, as this hardware, though important, is
+        relatively old and is produced in relatively low unit volumes.)
+2.      Do all eHCA-Infiniband-related work on other CPUs, including
+        interrupts.
+3.      Rework the eHCA driver so that its per-CPU kthreads are
+        provisioned only on selected CPUs.
+
+
+Name: irq/%d-%s
+Purpose: Handle threaded interrupts.
+To reduce its OS jitter, do the following:
+1.      Use irq affinity to force the irq threads to execute on
+        some other CPU.
+
+Name: kcmtpd_ctr_%d
+Purpose: Handle Bluetooth work.
+To reduce its OS jitter, do one of the following:
+1.      Don't use Bluetooth, in which case these kthreads won't be
+        created in the first place.
+2.      Use irq affinity to force Bluetooth-related interrupts to
+        occur on some other CPU and furthermore initiate all
+        Bluetooth activity on some other CPU.
+
+Name: ksoftirqd/%u
+Purpose: Execute softirq handlers when threaded or when under heavy load.
+To reduce its OS jitter, each softirq vector must be handled
+separately as follows:
+TIMER_SOFTIRQ:  Do all of the following:
+1.      To the extent possible, keep the CPU out of the kernel when it
+        is non-idle, for example, by avoiding system calls and by forcing
+        both kernel threads and interrupts to execute elsewhere.
+2.      Build with CONFIG_HOTPLUG_CPU=y.  After boot completes, force
+        the CPU offline, then bring it back online.  This forces
+        recurring timers to migrate elsewhere.  If you are concerned
+        with multiple CPUs, force them all offline before bringing the
+        first one back online.  Once you have onlined the CPUs in question,
+        do not offline any other CPUs, because doing so could force the
+        timer back onto one of the CPUs in question.
+NET_TX_SOFTIRQ and NET_RX_SOFTIRQ:  Do all of the following:
+1.      Force networking interrupts onto other CPUs.
+2.      Initiate any network I/O on other CPUs.
+3.      Once your application has started, prevent CPU-hotplug operations
+        from being initiated from tasks that might run on the CPU to
+        be de-jittered.  (It is OK to force this CPU offline and then
+        bring it back online before you start your application.)
+BLOCK_SOFTIRQ:  Do all of the following:
+1.      Force block-device interrupts onto some other CPU.
+2.      Initiate any block I/O on other CPUs.
+3.      Once your application has started, prevent CPU-hotplug operations
+        from being initiated from tasks that might run on the CPU to
+        be de-jittered.  (It is OK to force this CPU offline and then
+        bring it back online before you start your application.)
+BLOCK_IOPOLL_SOFTIRQ:  Do all of the following:
+1.      Force block-device interrupts onto some other CPU.
+2.      Initiate any block I/O and block-I/O polling on other CPUs.
+3.      Once your application has started, prevent CPU-hotplug operations
+        from being initiated from tasks that might run on the CPU to
+        be de-jittered.  (It is OK to force this CPU offline and then
+        bring it back online before you start your application.)
+TASKLET_SOFTIRQ: Do one or more of the following:
+1.      Avoid use of drivers that use tasklets.  (Such drivers will contain
+        calls to things like tasklet_schedule().)
+2.      Convert all drivers that you must use from tasklets to workqueues.
+3.      Force interrupts for drivers using tasklets onto other CPUs,
+        and also do I/O involving these drivers on other CPUs.
+SCHED_SOFTIRQ: Do all of the following:
+1.      Avoid sending scheduler IPIs to the CPU to be de-jittered,
+        for example, ensure that at most one runnable kthread is present
+        on that CPU.  If a thread that expects to run on the de-jittered
+        CPU awakens, the scheduler will send an IPI that can result in
+        a subsequent SCHED_SOFTIRQ.
+2.      Build with CONFIG_RCU_NOCB_CPU=y, CONFIG_RCU_NOCB_CPU_ALL=y,
+        CONFIG_NO_HZ_FULL=y, and, in addition, ensure that the CPU
+        to be de-jittered is marked as an adaptive-ticks CPU using the
+        "nohz_full=" boot parameter.  This reduces the number of
+        scheduler-clock interrupts that the de-jittered CPU receives,
+        minimizing its chances of being selected to do the load balancing
+        work that runs in SCHED_SOFTIRQ context.
+3.      To the extent possible, keep the CPU out of the kernel when it
+        is non-idle, for example, by avoiding system calls and by
+        forcing both kernel threads and interrupts to execute elsewhere.
+        This further reduces the number of scheduler-clock interrupts
+        received by the de-jittered CPU.
+HRTIMER_SOFTIRQ:  Do all of the following:
+1.      To the extent possible, keep the CPU out of the kernel when it
+        is non-idle.  For example, avoid system calls and force both
+        kernel threads and interrupts to execute elsewhere.
+2.      Build with CONFIG_HOTPLUG_CPU=y.  Once boot completes, force the
+        CPU offline, then bring it back online.  This forces recurring
+        timers to migrate elsewhere.  If you are concerned with multiple
+        CPUs, force them all offline before bringing the first one
+        back online.  Once you have onlined the CPUs in question, do not
+        offline any other CPUs, because doing so could force the timer
+        back onto one of the CPUs in question.
+RCU_SOFTIRQ:  Do at least one of the following:
+1.      Offload callbacks and keep the CPU in either dyntick-idle or
+        adaptive-ticks state by doing all of the following:
+        a.      Build with CONFIG_RCU_NOCB_CPU=y, CONFIG_RCU_NOCB_CPU_ALL=y,
+                CONFIG_NO_HZ_FULL=y, and, in addition ensure that the CPU
+                to be de-jittered is marked as an adaptive-ticks CPU using
+                the "nohz_full=" boot parameter.  Bind the rcuo kthreads
+                to housekeeping CPUs, which can tolerate OS jitter.
+        b.      To the extent possible, keep the CPU out of the kernel
+                when it is non-idle, for example, by avoiding system
+                calls and by forcing both kernel threads and interrupts
+                to execute elsewhere.
+2.      Enable RCU to do its processing remotely via dyntick-idle by
+        doing all of the following:
+        a.      Build with CONFIG_NO_HZ=y and CONFIG_RCU_FAST_NO_HZ=y.
+        b.      Ensure that the CPU goes idle frequently, allowing other
+                CPUs to detect that it has passed through an RCU quiescent
+                state.  If the kernel is built with CONFIG_NO_HZ_FULL=y,
+                userspace execution also allows other CPUs to detect that

+Name: rcuc/%u
+Purpose: Execute RCU callbacks in CONFIG_RCU_BOOST=y kernels.
+To reduce its OS jitter, do at least one of the following:
+1.      Build the kernel with CONFIG_PREEMPT=n.  This prevents these
+        kthreads from being created in the first place, and also obviates
+        the need for RCU priority boosting.  This approach is feasible
+        for workloads that do not require high degrees of responsiveness.
+2.      Build the kernel with CONFIG_RCU_BOOST=n.  This prevents these
+        kthreads from being created in the first place.  This approach
+        is feasible only if your workload never requires RCU priority
+        boosting, for example, if you ensure frequent idle time on all
+        CPUs that might execute within the kernel.
+3.      Build with CONFIG_RCU_NOCB_CPU=y and CONFIG_RCU_NOCB_CPU_ALL=y,
+        which offloads all RCU callbacks to kthreads that can be moved
+        off of CPUs susceptible to OS jitter.  This approach prevents the
+        rcuc/%u kthreads from having any work to do, so that they are
+        never awakened.
+4.      Ensure that the CPU never enters the kernel, and, in particular,
+        avoid initiating any CPU hotplug operations on this CPU.  This is
+        another way of preventing any callbacks from being queued on the
+        CPU, again preventing the rcuc/%u kthreads from having any work
+        to do.
+
+Name: rcuob/%d, rcuop/%d, and rcuos/%d
+Purpose: Offload RCU callbacks from the corresponding CPU.
+To reduce its OS jitter, do at least one of the following:
+1.      Use affinity, cgroups, or other mechanism to force these kthreads
+        to execute on some other CPU.
+2.      Build with CONFIG_RCU_NOCB_CPUS=n, which will prevent these
+        kthreads from being created in the first place.  However, please
+        note that this will not eliminate OS jitter, but will instead
+        shift it to RCU_SOFTIRQ.
+
+Name: watchdog/%u
+Purpose: Detect software lockups on each CPU.
+To reduce its OS jitter, do at least one of the following:
+1.      Build with CONFIG_LOCKUP_DETECTOR=n, which will prevent these
+        kthreads from being created in the first place.
+2.      Echo a zero to /proc/sys/kernel/watchdog to disable the
+        watchdog timer.
+3.      Echo a large number of /proc/sys/kernel/watchdog_thresh in
+        order to reduce the frequency of OS jitter due to the watchdog
+        timer down to a level that is acceptable for your workload.

 4. Enumeration and Discovery
 ----------------------------
 
-When rio_init_mports() is called it scans a list of registered master ports and
-calls an enumeration or discovery routine depending on the configured role of a
-master port: host or agent.
+4.1 Overview
+------------
+
+RapidIO subsystem configuration options allow users to specify enumeration and
+discovery methods as statically linked components or loadable modules.
+An enumeration/discovery method implementation and available input parameters
+define how any given method can be attached to available RapidIO mports:
+simply to all available mports OR individually to the specified mport device.
+
+Depending on selected enumeration/discovery build configuration, there are
+several methods to initiate an enumeration and/or discovery process:
+
+  (a) Statically linked enumeration and discovery process can be started
+  automatically during kernel initialization time using corresponding module
+  parameters. This was the original method used since introduction of RapidIO
+  subsystem. Now this method relies on enumerator module parameter which is
+  'rio-scan.scan' for existing basic enumeration/discovery method.
+  When automatic start of enumeration/discovery is used a user has to ensure
+  that all discovering endpoints are started before the enumerating endpoint
+  and are waiting for enumeration to be completed.
+  Configuration option CONFIG_RAPIDIO_DISC_TIMEOUT defines time that discovering
+  endpoint waits for enumeration to be completed. If the specified timeout
+  expires the discovery process is terminated without obtaining RapidIO network
+  information. NOTE: a timed out discovery process may be restarted later using
+  a user-space command as it is described later if the given endpoint was
+  enumerated successfully.
+
+  (b) Statically linked enumeration and discovery process can be started by
+  a command from user space. This initiation method provides more flexibility
+  for a system startup compared to the option (a) above. After all participating
+  endpoints have been successfully booted, an enumeration process shall be
+  started first by issuing a user-space command, after an enumeration is
+  completed a discovery process can be started on all remaining endpoints.
+
+  (c) Modular enumeration and discovery process can be started by a command from
+  user space. After an enumeration/discovery module is loaded, a network scan
+  process can be started by issuing a user-space command.
+  Similar to the option (b) above, an enumerator has to be started first.
+
+  (d) Modular enumeration and discovery process can be started by a module
+  initialization routine. In this case an enumerating module shall be loaded
+  first.
+
+When a network scan process is started it calls an enumeration or discovery
+routine depending on the configured role of a master port: host or agent.

+4.2 Automatic Start of Enumeration and Discovery
+------------------------------------------------
+
+Automatic enumeration/discovery start method is applicable only to built-in
+enumeration/discovery RapidIO configuration selection. To enable automatic
+enumeration/discovery start by existing basic enumerator method set use boot
+command line parameter "rio-scan.scan=1".
+
+This configuration requires synchronized start of all RapidIO endpoints that
+form a network which will be enumerated/discovered. Discovering endpoints have
+to be started before an enumeration starts to ensure that all RapidIO
+controllers have been initialized and are ready to be discovered. Configuration
+parameter CONFIG_RAPIDIO_DISC_TIMEOUT defines time (in seconds) which
+a discovering endpoint will wait for enumeration to be completed.
+
+When automatic enumeration/discovery start is selected, basic method's
+initialization routine calls rio_init_mports() to perform enumeration or
+discovery for all known mport devices.
+
+Depending on RapidIO network size and configuration this automatic
+enumeration/discovery start method may be difficult to use due to the
+requirement for synchronized start of all endpoints.
+
+4.3 User-space Start of Enumeration and Discovery
+-------------------------------------------------
+
+User-space start of enumeration and discovery can be used with built-in and
+modular build configurations. For user-space controlled start RapidIO subsystem
+creates the sysfs write-only attribute file '/sys/bus/rapidio/scan'. To initiate
+an enumeration or discovery process on specific mport device, a user needs to
+write mport_ID (not RapidIO destination ID) into that file. The mport_ID is a
+sequential number (0 ... RIO_MAX_MPORTS) assigned during mport device
+registration. For example for machine with single RapidIO controller, mport_ID
+for that controller always will be 0.
+
+To initiate RapidIO enumeration/discovery on all available mports a user may
+write '-1' (or RIO_MPORT_ANY) into the scan attribute file.
+
+4.4 Basic Enumeration Method
+----------------------------
+
+This is an original enumeration/discovery method which is available since
+first release of RapidIO subsystem code. The enumeration process is
+implemented according to the enumeration algorithm outlined in the RapidIO
+Interconnect Specification: Annex I [1].
+
+This method can be configured as statically linked or loadable module.
+The method's single parameter "scan" allows to trigger the enumeration/discovery
+process from module initialization routine.
+
+This enumeration/discovery method can be started only once and does not support
+unloading if it is built as a module.

+
+RapidIO subsystem code organization allows addition of new enumeration/discovery
+methods as new configuration options without significant impact to to the core
+RapidIO code.
+
+A new enumeration/discovery method has to be attached to one or more mport

+                        RAMSTER HOW-TO
+
+Author: Dan Magenheimer
+Ramster maintainer: Konrad Wilk <konrad.wilk@oracle.com>
+
+This is a HOWTO document for ramster which, as of this writing, is in
+the kernel as a subdirectory of zcache in drivers/staging, called ramster.
+(Zcache can be built with or without ramster functionality.)  If enabled
+and properly configured, ramster allows memory capacity load balancing
+across multiple machines in a cluster.  Further, the ramster code serves
+as an example of asynchronous access for zcache (as well as cleancache and
+frontswap) that may prove useful for future transcendent memory
+implementations, such as KVM and NVRAM.  While ramster works today on
+any network connection that supports kernel sockets, its features may
+become more interesting on future high-speed fabrics/interconnects.
+
+Ramster requires both kernel and userland support.  The userland support,
+called ramster-tools, is known to work with EL6-based distros, but is a
+set of poorly-hacked slightly-modified cluster tools based on ocfs2, which
+includes an init file, a config file, and a userland binary that interfaces
+to the kernel.  This state of userland support reflects the abysmal userland
+skills of this suitably-embarrassed author; any help/patches to turn
+ramster-tools into more distributable rpms/debs useful for a wider range
+of distros would be appreciated.  The source RPM that can be used as a
+starting point is available at:
+    http://oss.oracle.com/projects/tmem/files/RAMster/ 
+
+As a result of this author's ignorance, userland setup described in this
+HOWTO assumes an EL6 distro and is described in EL6 syntax.  Apologies
+if this offends anyone!
+
+Kernel support has only been tested on x86_64.  Systems with an active
+ocfs2 filesystem should work, but since ramster leverages a lot of
+code from ocfs2, there may be latent issues.  A kernel configuration that
+includes CONFIG_OCFS2_FS should build OK, and should certainly run OK
+if no ocfs2 filesystem is mounted.
+
+This HOWTO demonstrates memory capacity load balancing for a two-node
+cluster, where one node called the "local" node becomes overcommitted
+and the other node called the "remote" node provides additional RAM
+capacity for use by the local node.  Ramster is capable of more complex
+topologies; see the last section titled "ADVANCED RAMSTER TOPOLOGIES".
+
+If you find any terms in this HOWTO unfamiliar or don't understand the
+motivation for ramster, the following LWN reading is recommended:
+-- Transcendent Memory in a Nutshell (lwn.net/Articles/454795)
+-- The future calculus of memory management (lwn.net/Articles/475681)
+And since ramster is built on top of zcache, this article may be helpful:
+-- In-kernel memory compression (lwn.net/Articles/545244)
+
+Now that you've memorized the contents of those articles, let's get started!
+
+A. PRELIMINARY
+
+1) Install two x86_64 Linux systems that are known to work when
+   upgraded to a recent upstream Linux kernel version.
+
+On each system:
+
+2) Configure, build and install, then boot Linux, just to ensure it
+   can be done with an unmodified upstream kernel.  Confirm you booted
+   the upstream kernel with "uname -a".
+
+3) If you plan to do any performance testing or unless you plan to
+   test only swapping, the "WasActive" patch is also highly recommended.
+   (Search lkml.org for WasActive, apply the patch, rebuild your kernel.)
+   For a demo or simple testing, the patch can be ignored.
+
+4) Install ramster-tools as root.  An x86_64 rpm for EL6-based systems
+   can be found at:
+    http://oss.oracle.com/projects/tmem/files/RAMster/ 
+   (Sorry but for now, non-EL6 users must recreate ramster-tools on
+   their own from source.  See above.)
+
+5) Ensure that debugfs is mounted at each boot.  Examples below assume it
+   is mounted at /sys/kernel/debug.
+
+B. BUILDING RAMSTER INTO THE KERNEL
+
+Do the following on each system:
+
+1) Using the kernel configuration mechanism of your choice, change
+   your config to include:
+
+        CONFIG_CLEANCACHE=y
+        CONFIG_FRONTSWAP=y
+        CONFIG_STAGING=y
+        CONFIG_CONFIGFS_FS=y # NOTE: MUST BE y, not m
+        CONFIG_ZCACHE=y
+        CONFIG_RAMSTER=y
+
+   For a linux-3.10 or later kernel, you should also set:
+
+        CONFIG_ZCACHE_DEBUG=y
+        CONFIG_RAMSTER_DEBUG=y
+
+   Before building the kernel please doublecheck your kernel config
+   file to ensure all of the settings are correct.
+
+2) Build this kernel and change your boot file (e.g. /etc/grub.conf)
+   so that the new kernel will boot.
+
+3) Add "zcache" and "ramster" as kernel boot parameters for the new kernel.
+
+4) Reboot each system approximately simultaneously.
+
+5) Check dmesg to ensure there are some messages from ramster, prefixed
+   by "ramster:"
+
+        # dmesg | grep ramster
+
+   You should also see a lot of files in:
+
+        # ls /sys/kernel/debug/zcache
+        # ls /sys/kernel/debug/ramster
+
+   These are mostly counters for various zcache and ramster activities.
+   You should also see files in:
+
+        # ls /sys/kernel/mm/ramster
+
+   These are sysfs files that control ramster as we shall see.
+
+   Ramster now will act as a single-system zcache on each system
+   but doesn't yet know anything about the cluster so can't yet do
+   anything remotely.
+
+C. CONFIGURING THE RAMSTER CLUSTER
+
+This part can be error prone unless you are familiar with clustering
+filesystems.  We need to describe the cluster in a /etc/ramster.conf
+file and the init scripts that parse it are extremely picky about
+the syntax.
+
+1) Create a /etc/ramster.conf file and ensure it is identical on both
+   systems.  This file mimics the ocfs2 format and there is a good amount
+   of documentation that can be searched for ocfs2.conf, but you can use:
+
+        cluster:
+                name = ramster
+                node_count = 2
+        node:
+                name = system1
+                cluster = ramster
+                number = 0
+                ip_address = my.ip.ad.r1
+                ip_port = 7777
+        node:
+                name = system2
+                cluster = ramster
+                number = 1
+                ip_address = my.ip.ad.r2
+                ip_port = 7777
+
+   You must ensure that the "name" field in the file exactly matches
+   the output of "hostname" on each system; if "hostname" shows a
+   fully-qualified hostname, ensure the name is fully qualified in
+   /etc/ramster.conf.  Obviously, substitute my.ip.ad.rx with proper
+   ip addresses.
+
+2) Enable the ramster service and configure it.  If you used the
+   EL6 ramster-tools, this would be:
+
+        # chkconfig --add ramster
+        # service ramster configure
+
+   Set "load on boot" to "y", cluster to start is "ramster" (or whatever
+   name you chose in ramster.conf), heartbeat dead threshold as "500",
+   network idle timeout as "1000000".  Leave the others as default.
+
+3) Reboot both systems.  After reboot, try (assuming EL6 ramster-tools):
+
+        # service ramster status
+
+   You should see "Checking RAMSTER cluster "ramster": Online".  If you do
+   not, something is wrong and ramster will not work.  Note that you
+   should also see that the driver for "configfs" is loaded and mounted,
+   the driver for ocfs2_dlmfs is not loaded, and some numbers for network
+   parameters.  You will also see "Checking RAMSTER heartbeat: Not active".
+   That's all OK.
+
+4) Now you need to start the cluster heartbeat; the cluster is not "up"
+   until all nodes detect a heartbeat.  In a real cluster, heartbeat detection
+   is done via a cluster filesystem, but ramster doesn't require one.  Some
+   hack-y kernel code in ramster can start the heartbeat for you though if
+   you tell it what nodes are "up".  To enable the heartbeat, do:
+
+        # echo 0 > /sys/kernel/mm/ramster/manual_node_up
+        # echo 1 > /sys/kernel/mm/ramster/manual_node_up
+
+   This must be done on BOTH nodes and, to avoid timeouts, must be done
+   approximately concurrently on both nodes.  On an EL6 system, it is
+   convenient to put these lines in /etc/rc.local.  To confirm that the
+   cluster is now up, on both systems do:
+
+        # dmesg | grep ramster
+
+   You should see ramster "Accepted connection" messages in dmesg on both
+   nodes after this.  Note that if you check userland status again with
+
+        # service ramster status
+
+   you will still see "Checking RAMSTER heartbeat: Not active".  That's
+   still OK... the ramster kernel heartbeat hack doesn't communicate to
+   userland.
+
+5) You now must tell each node the node to which it should "remotify" pages.
+   On this two node cluster, we will assume the "local" node, node 0, has
+   memory overcommitted and will use ramster to utilize RAM capacity on
+   the "remote node", node 1.  To configure this, on node 0, you do:
+
+        # echo 1 > /sys/kernel/mm/ramster/remote_target_nodenum
+
+   You should see "ramster: node 1 set as remotification target" in dmesg
+   on node 0.  Again, on EL6, /etc/rc.local is a good place to put this
+   on node 0 so you don't forget to do it at each boot.
+
+6) One more step:  By default, the ramster code does not "remotify" any
+   pages; this is primarily for testing purposes, but sometimes it is
+   useful.  This may change in the future, but for now, on node 0, you do:
+
+        # echo 1 > /sys/kernel/mm/ramster/pers_remotify_enable
+        # echo 1 > /sys/kernel/mm/ramster/eph_remotify_enable
+
+   The first enables remotifying swap (persistent, aka frontswap) pages,
+   the second enables remotifying of page cache (ephemeral, cleancache)
+   pages.
+
+   On EL6, these lines can also be put in /etc/rc.local (AFTER the
+   node_up lines), or at the beginning of a script that runs a workload.
+
+7) Note that most testing has been done with both/all machines booted
+   roughly simultaneously to avoid cluster timeouts.  Ideally, you should
+   do this too unless you are trying to break ramster rather than just
+   use it. ;-)
+
+D. TESTING RAMSTER
+
+1) Note that ramster has no value unless pages get "remotified".  For
+   swap/frontswap/persistent pages, this doesn't happen unless/until
+   the workload would cause swapping to occur, at which point pages
+   are put into frontswap/zcache, and the remotification thread starts
+   working.  To get to the point where the system swaps, you either
+   need a workload for which the working set exceeds the RAM in the
+   system; or you need to somehow reduce the amount of RAM one of
+   the system sees.  This latter is easy when testing in a VM, but
+   harder on physical systems.  In some cases, "mem=xxxM" on the
+   kernel command line restricts memory, but for some values of xxx
+   the kernel may fail to boot.  One may also try creating a fixed
+   RAMdisk, doing nothing with it, but ensuring that it eats up a fixed
+   amount of RAM.
+
+2) To see if ramster is working, on the "remote node", node 1, try:
+
+        # grep . /sys/kernel/debug/ramster/foreign_*
+        # # note, that is space-dot-space between grep and the pathname
+
+   to monitor the number (and max) ephemeral and persistent pages
+   that ramster has sent.  If these stay at zero, ramster is not working
+   either because the workload on the local node (node 0) isn't creating
+   enough memory pressure or because "remotifying" isn't working.  On the
+   local system, node 0, you can watch lots of useful information also.
+   Try:
+
+        grep . /sys/kernel/debug/zcache/*pageframes* \
+                /sys/kernel/debug/zcache/*zbytes* \
+                /sys/kernel/debug/zcache/*zpages* \
+                /sys/kernel/debug/ramster/*remote*
+
+   Of particular note are the remote_*_pages_succ_get counters.  These
+   show how many disk reads and/or disk writes have been avoided on the
+   overcommitted local system by storing pages remotely using ramster.
+
+   At the risk of information overload, you can also grep:
+
+        /sys/kernel/debug/cleancache/* and /sys/kernel/debug/frontswap/*
+
+   These show, for example, how many disk reads and/or disk writes have
+   been avoided by using zcache to optimize RAM on the local system.
+
+
+AUTOMATIC SWAP REPATRIATION
+
+You may notice that while the systems are idle, the foreign persistent
+page count on the remote machine slowly decreases.  This is because
+ramster implements "frontswap selfshrinking":  When possible, swap
+pages that have been remotified are slowly repatriated to the local
+machine.  This is so that local RAM can be used when possible and
+so that, in case of remote machine crash, the probability of loss
+of data is reduced.
+
+REBOOTING / POWEROFF
+
+If a system is shut down while some of its swap pages still reside
+on a remote system, the system may lock up during the shutdown
+sequence.  This will occur if the network is shut down before the
+swap mechansim is shut down, which is the default ordering on many
+distros.  To avoid this annoying problem, simply shut off the swap
+subsystem before starting the shutdown sequence, e.g.:
+
+        # swapoff -a
+        # reboot
+
+Ideally, this swapoff-before-ifdown ordering should be enforced permanently
+using shutdown scripts.
+
+KNOWN PROBLEMS
+
+1) You may periodically see messages such as:
+
+    ramster_r2net, message length problem
+
+   This is harmless but indicates that a node is sending messages
+   containing compressed pages that exceed the maximum for zcache
+   (PAGE_SIZE*15/16).  The sender side needs to be fixed.
+
+2) If you see a "No longer connected to node..." message or a "No connection
+   established with node X after N seconds", it is possible you may
+   be in an unrecoverable state.  If you are certain all of the
+   appropriate cluster configuration steps described above have been
+   performed, try rebooting the two servers concurrently to see if
+   the cluster starts.
+
+   Note that "Connection to node... shutdown, state 7" is an intermediate
+   connection state.  As long as you later see "Accepted connection", the
+   intermediate states are harmless.
+
+3) There are known issues in counting certain values.  As a result
+   you may see periodic warnings from the kernel.  Almost always you
+   will see "ramster: bad accounting for XXX".  There are also "WARN_ONCE"
+   messages.  If you see kernel warnings with a tombstone, please report
+   them.  They are harmless but reflect bugs that need to be eventually fixed.
+
+ADVANCED RAMSTER TOPOLOGIES
+
+The kernel code for ramster can support up to eight nodes in a cluster,
+but no testing has been done with more than three nodes.
+
+In the example described above, the "remote" node serves as a RAM
+overflow for the "local" node.  This can be made symmetric by appropriate
+settings of the sysfs remote_target_nodenum file.  For example, by setting:
+
+        # echo 1 > /sys/kernel/mm/ramster/remote_target_nodenum
+
+on node 0, and
+
+        # echo 0 > /sys/kernel/mm/ramster/remote_target_nodenum
+
+on node 1, each node can serve as a RAM overflow for the other.
+
+For more than two nodes, a "RAM server" can be configured.  For a
+three node system, set:
+
+        # echo 0 > /sys/kernel/mm/ramster/remote_target_nodenum
+
+on node 1, and
+
+        # echo 0 > /sys/kernel/mm/ramster/remote_target_nodenum
+
+on node 2.  Then node 0 is a RAM server for node 1 and node 2.
+
+In this implementation of ramster, any remote node is potentially a single
+point of failure (SPOF).  Though the probability of failure is reduced
+by automatic swap repatriation (see above), a proposed future enhancement
+to ramster improves high-availability for the cluster by sending a copy
+of each page of date to two other nodes.  Patches welcome!

+          Byte_t Frequency: A flag identifying the frequency
+                   of the periodic interrupt, can be any one of the following:
+                      FREQ_DIS - periodic interrupt disabled
+                      FREQ_137HZ - 137 Hertz

+                      FREQ_4HZ - 4 Hertz
+                   If IRQNum is set to 0 the Frequency parameter is

+          int PeriodicOnly: 1 if all interrupts except the periodic
+                               interrupt are to be blocked.
+                            0 is both the periodic interrupt and
+                               other channel interrupts are allowed.
+                            If IRQNum is set to 0 the PeriodicOnly parameter is
+                               overidden, it is forced to a value of 0.
+Return:   int: Number of AIOPs on the controller, or CTLID_NULL if controller
+               initialization failed.
+
+Comments:
+          If periodic interrupts are to be disabled but AIOP interrupts
+          are allowed, set Frequency to FREQ_DIS and PeriodicOnly to 0.
+
+          If interrupts are to be completely disabled set IRQNum to 0.
+
+          Setting Frequency to FREQ_DIS and PeriodicOnly to 1 is an
+          invalid combination.
+
+          This function performs initialization of global interrupt modes,
+          but it does not actually enable global interrupts.  To enable
+          and disable global interrupts use functions sEnGlobalInt() and
+          sDisGlobalInt().  Enabling of global interrupts is normally not
+          done until all other initializations are complete.
+
+          Even if interrupts are globally enabled, they must also be
+          individually enabled for each channel that is to generate
+          interrupts.
+
+Warnings: No range checking on any of the parameters is done.
+
+          No context switches are allowed while executing this function.
+
+          After this function all AIOPs on the controller are disabled,
+          they can be enabled with sEnAiop().

+ * Sort the log items in the transaction.
+ *
+ * The ordering constraints are defined by the inode allocation and unlink
+ * behaviour. The rules are:
+ *
+ *      1. Every item is only logged once in a given transaction. Hence it
+ *         represents the last logged state of the item. Hence ordering is
+ *         dependent on the order in which operations need to be performed so
+ *         required initial conditions are always met.
+ *
+ *      2. Cancelled buffers are recorded in pass 1 in a separate table and
+ *         there's nothing to replay from them so we can simply cull them
+ *         from the transaction. However, we can't do that until after we've
+ *         replayed all the other items because they may be dependent on the
+ *         cancelled buffer and replaying the cancelled buffer can remove it
+ *         form the cancelled buffer table. Hence they have tobe done last.
+ *
+ *      3. Inode allocation buffers must be replayed before inode items that
+ *         read the buffer and replay changes into it.
+ *
+ *      4. Inode unlink buffers must be replayed after inode items are replayed.
+ *         This ensures that inodes are completely flushed to the inode buffer
+ *         in a "free" state before we remove the unlinked inode list pointer.
+ *
+ * Hence the ordering needs to be inode allocation buffers first, inode items
+ * second, inode unlink buffers third and cancelled buffers last.
+ *
+ * But there's a problem with that - we can't tell an inode allocation buffer
+ * apart from a regular buffer, so we can't separate them. We can, however,
+ * tell an inode unlink buffer from the others, and so we can separate them out
+ * from all the other buffers and move them to last.
+ *
+ * Hence, 4 lists, in order from head to tail:
+ *      - buffer_list for all buffers except cancelled/inode unlink buffers
+ *      - item_list for all non-buffer items
+ *      - inode_buffer_list for inode unlink buffers
+ *      - cancel_list for the cancelled buffers

+       function.
+     - If this state is a consistent state with a default action, then
+       the only way this function was invoked is if the default action
+       is an error action.  In that case, don't check for expected
+       tokens because there are none.
+     - The only way there can be no lookahead present (in yychar) is if
+       this state is a consistent state with a default action.  Thus,
+       detecting the absence of a lookahead is sufficient to determine
+       that there is no unexpected or expected token to report.  In that
+       case, just report a simple "syntax error".
+     - Don't assume there isn't a lookahead just because this state is a
+       consistent state with a default action.  There might have been a
+       previous inconsistent state, consistent state with a non-default
+       action, or user semantic action that manipulated yychar.
+     - Of course, the expected token list depends on states to have
+       correct lookahead information, and it depends on the parser not
+       to perform extra reductions after fetching a lookahead from the
+       scanner and before detecting a syntax error.  Thus, state merging
+       (from LALR or IELR) and default reductions corrupt the expected
+       token list.  However, the list is correct for canonical LR with
+       one exception: it will still contain any token that will not be
+       accepted due to an error action in a later state.
