+CPU load
+--------
+
+Linux exports various bits of information via `/proc/stat' and
+`/proc/uptime' that userland tools, such as top(1), use to calculate
+the average time system spent in a particular state, for example:
+
+ $ iostat
+ Linux 2.6.18.3-exp (linmac) 02/20/2007
+
+ avg-cpu: %user %nice %system %iowait %steal %idle
+ 10.01 0.00 2.92 5.44 0.00 81.63
+
+ ...
+
+Here the system thinks that over the default sampling period the
+system spent 10.01% of the time doing work in user space, 2.92% in the
+kernel, and was overall 81.63% of the time idle.
+
+In most cases the `/proc/stat' information reflects the reality quite
+closely, however due to the nature of how/when the kernel collects
+this data sometimes it can not be trusted at all.
+
+So how is this information collected? Whenever timer interrupt is
+signalled the kernel looks what kind of task was running at this
+moment and increments the counter that corresponds to this tasks
+kind/state. The problem with this is that the system could have
+switched between various states multiple times between two timer
+interrupts yet the counter is incremented only for the last state.
+
+
+Example
+-------
+
+If we imagine the system with one task that periodically burns cycles
+in the following manner:
+
+ time line between two timer interrupts
+|--------------------------------------|
+ ^ ^
+ |_ something begins working |
+ |_ something goes to sleep
+ (only to be awaken quite soon)
+
+In the above situation the system will be 0% loaded according to the
+`/proc/stat' (since the timer interrupt will always happen when the
+system is executing the idle handler), but in reality the load is
+closer to 99%.
+
+One can imagine many more situations where this behavior of the kernel
+will lead to quite erratic information inside `/proc/stat'.

+Description
+-----------
+
+rchar
+-----
+
+I/O counter: chars read
+The number of bytes which this task has caused to be read from storage. This
+is simply the sum of bytes which this process passed to read() and pread().
+It includes things like tty IO and it is unaffected by whether or not actual
+physical disk IO was required (the read might have been satisfied from
+pagecache)
+
+
+wchar
+-----
+
+I/O counter: chars written
+The number of bytes which this task has caused, or shall cause to be written
+to disk. Similar caveats apply here as with rchar.
+
+
+syscr
+-----
+
+I/O counter: read syscalls
+Attempt to count the number of read I/O operations, i.e. syscalls like read()
+and pread().
+
+
+syscw
+-----
+
+I/O counter: write syscalls
+Attempt to count the number of write I/O operations, i.e. syscalls like
+write() and pwrite().
+
+
+read_bytes
+----------
+
+I/O counter: bytes read
+Attempt to count the number of bytes which this process really did cause to
+be fetched from the storage layer. Done at the submit_bio() level, so it is
+accurate for block-backed filesystems. <please add status regarding NFS and
+CIFS at a later time>
+
+
+write_bytes
+-----------
+
+I/O counter: bytes written
+Attempt to count the number of bytes which this process caused to be sent to
+the storage layer. This is done at page-dirtying time.
+
+
+cancelled_write_bytes
+---------------------
+
+The big inaccuracy here is truncate. If a process writes 1MB to a file and
+then deletes the file, it will in fact perform no writeout. But it will have
+been accounted as having caused 1MB of write.
+In other words: The number of bytes which this process caused to not happen,
+by truncating pagecache. A task can cause "negative" IO too. If this task
+truncates some dirty pagecache, some IO which another task has been accounted
+for (in it's write_bytes) will not be happening. We _could_ just subtract that
+from the truncating task's write_bytes, but there is information loss in doing
+that.
+
+
+Note
+----
+
+At its current implementation state, this is a bit racy on 32-bit machines: if
+process A reads process B's /proc/pid/io while process B is updating one of
+those 64-bit counters, process A could see an intermediate result.
+
+
+More information about this can be found within the taskstats documentation in
+Documentation/accounting.

when the IRQ is edge-triggered.
+Emulating Open Drain Signals
+----------------------------
+Sometimes shared signals need to use "open drain" signaling, where only the
+low signal level is actually driven. (That term applies to CMOS transistors;
+"open collector" is used for TTL.) A pullup resistor causes the high signal
+level. This is sometimes called a "wire-AND"; or more practically, from the
+negative logic (low=true) perspective this is a "wire-OR".
+
+One common example of an open drain signal is a shared active-low IRQ line.
+Also, bidirectional data bus signals sometimes use open drain signals.
+
+Some GPIO controllers directly support open drain outputs; many don't. When
+you need open drain signaling but your hardware doesn't directly support it,
+there's a common idiom you can use to emulate it with any GPIO pin that can
+be used as either an input or an output:
+
+ LOW: gpio_direction_output(gpio, 0) ... this drives the signal
+ and overrides the pullup.
+
+ HIGH: gpio_direction_input(gpio) ... this turns off the output,
+ so the pullup (or some other device) controls the signal.
+
+If you are "driving" the signal high but gpio_get_value(gpio) reports a low
+value (after the appropriate rise time passes), you know some other component
+is driving the shared signal low. That's not necessarily an error. As one
+common example, that's how I2C clocks are stretched: a slave that needs a
+slower clock delays the rising edge of SCK, and the I2C master adjusts its
+signaling rate accordingly.
+

Select this option, if you want to share the text segment of the
Linux kernel between different VM guests. This reduces memory
usage with lots of guests but greatly increases kernel size.
+ Also if a kernel was IPL'ed from a shared segment the kexec system

You should only select this option if you know what you are
doing and want to exploit this feature.

- The initial RAM filesystem is a ramfs which is loaded by the
- boot loader (loadlin or lilo) and that is mounted as root
- before the normal boot procedure. It is typically used to
- load modules needed to mount the "real" root file system,

- If RAM disk support (BLK_DEV_RAM) is also included, this

+------------
+Fix mtime bouncing around from local idea of last write times to remote time.
+Fix hang (in i_size_read) when simultaneous size update of same remote file
+on smp system corrupts sequence number. Do not reread unnecessarily partial page
+(which we are about to overwrite anyway) when writing out file opened rw.
+When DOS attribute of file on non-Unix server's file changes on the server side
+from read-only back to read-write, reflect this change in default file mode
+(we had been leaving a file's mode read-only until the inode were reloaded).
+Allow setting of attribute back to ATTR_NORMAL (removing readonly dos attribute
+when archive dos attribute not set and we are changing mode back to writeable
+on server which does not support the Unix Extensions).
+
Version 1.47
------------
Fix oops in list_del during mount caused by unaligned string.

- Enable the possibility of suspending the machine.
- It doesn't need ACPI or APM.
- You may suspend your machine by 'swsusp' or 'shutdown -z <time>'
- (patch for sysvinit needed).
+ Enable the suspend to disk (STD) functionality.
- It creates an image which is saved in your active swap. Upon next
+ You can suspend your machine with 'echo disk > /sys/power/state'.
+ Alternatively, you can use the additional userland tools available
+ from <http://suspend.sf.net>.
+
+ In principle it does not require ACPI or APM, although for example
+ ACPI will be used if available.
+
+ It creates an image which is saved in your active swap. Upon the next
boot, pass the 'resume=/dev/swappartition' argument to the kernel to
have it detect the saved image, restore memory state from it, and
continue to run as before. If you do not want the previous state to
- be reloaded, then use the 'noresume' kernel argument. However, note
- that your partitions will be fsck'd and you must re-mkswap your swap
- partitions. It does not work with swap files.
+ be reloaded, then use the 'noresume' kernel command line argument.
+ Note, however, that fsck will be run on your filesystems and you will
+ need to run mkswap against the swap partition used for the suspend.
- Right now you may boot without resuming and then later resume but
- in meantime you cannot use those swap partitions/files which were
- involved in suspending. Also in this case there is a risk that buffers
- on disk won't match with saved ones.
+ It also works with swap files to a limited extent (for details see
+ <file:Documentation/power/swsusp-and-swap-files.txt>).
+
+ Right now you may boot without resuming and resume later but in the
+ meantime you cannot use the swap partition(s)/file(s) involved in
+ suspending. Also in this case you must not use the filesystems
+ that were mounted before the suspend. In particular, you MUST NOT
+ MOUNT any journaled filesystems mounted before the suspend or they
+ will get corrupted in a nasty way.
For more information take a look at <file:Documentation/power/swsusp.txt>.
- (For now, swsusp is incompatible with PAE aka HIGHMEM_64G on i386.
- we need identity mapping for resume to work, and that is trivial
- to get with 4MB pages, but less than trivial on PAE).

-/* SECURE SOCKET IMPLEMENTATION
- *
- * TRANSMIT:
- *
- * When the user sends a packet via send() system call
- * the wanpipe_sendmsg() function is executed.
- *
- * Each packet is enqueud into sk->sk_write_queue transmit
- * queue. When the packet is enqueued, a delayed transmit
- * timer is triggerd which acts as a Bottom Half hander.
- *
- * wanpipe_delay_transmit() function (BH), dequeues packets
- * from the sk->sk_write_queue transmit queue and sends it
- * to the deriver via dev->hard_start_xmit(skb, dev) function.
- * Note, this function is actual a function pointer of if_send()
- * routine in the wanpipe driver.
- *
- * X25API GUARANTEED DELIVERY:
- *
- * In order to provide 100% guaranteed packet delivery,
- * an atomic 'packet_sent' counter is implemented. Counter
- * is incremented for each packet enqueued
- * into sk->sk_write_queue. Counter is decremented each
- * time wanpipe_delayed_transmit() function successfuly
- * passes the packet to the driver. Before each send(), a poll
- * routine checks the sock resources The maximum value of
- * packet sent counter is 1, thus if one packet is queued, the
- * application will block until that packet is passed to the
- * driver.
- *
- * RECEIVE:
- *
- * Wanpipe device drivers call the socket bottom half
- * function, wanpipe_rcv() to queue the incoming packets
- * into an AF_WANPIPE socket queue. Based on wanpipe_rcv()
- * return code, the driver knows whether the packet was
- * successfully queued. If the socket queue is full,
- * protocol flow control is used by the driver, if any,
- * to slow down the traffic until the sock queue is free.
- *
- * Every time a packet arrives into a socket queue the
- * socket wakes up processes which are waiting to receive
- * data.
- *
- * If the socket queue is full, the driver sets a block
- * bit which signals the socket to kick the wanpipe driver
- * bottom half hander when the socket queue is partialy
- * empty. wanpipe_recvmsg() function performs this action.
- *
- * In case of x25api, packets will never be dropped, since
- * flow control is available.
- *
- * In case of streaming protocols like CHDLC, packets will
- * be dropped but the statistics will be generated.
- */

-
-/* The code below is used to test memory leaks. It prints out
- * a message every time kmalloc and kfree system calls get executed.
- * If the calls match there is no leak :)
