Who: Richard Purdie <rpurdie@rpsys.net>
---------------------------
+
+What: Wireless extensions over netlink (CONFIG_NET_WIRELESS_RTNETLINK)
+When: with the merge of wireless-dev, 2.6.22 or later
+Why: The option/code is
+ * not enabled on most kernels
+ * not required by any userspace tools (except an experimental one,
+ and even there only for some parts, others use ioctl)
+ * pointless since wext is no longer evolving and the ioctl
+ interface needs to be kept

+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.

---help---
- 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).
