batctl uses /dev/batman-adv to send special batman-adv icmp packets to
other nodes in the mesh. To get it working with multiple batX devices we
must ensure that every mesh device can have their own socket which is
used to inject those packets in exactly one mesh.
The current implementation still doesn't allow to use complete separated
meshes as we rely on structures which are not part of the private data
of a batman device.

Switch driver over from wext to cfg80211 interface.
Some Notes:
- This patch moves the driver wholesale from wext to cfg80211. Wext
support is still provided through the cfg80211 provided wext
compatability layer.
- Currently only infrastructure mode is implemented. Ad hoc mode is not
yet implemented, but can be added.
- It does not support connecting to a specified bssid, instead roaming
is handled by the card itself. This matches the behaviour of the
existing driver.
- It has been tested using NetworkManager (via wpa_supplicant)
configured to use the wext compatability layer, and then again with the
native nl80211 layer.

The current code creates directories in procfs named after interfaces,
but doesn't handle renaming. This can result in name collisions and
consequent WARNINGs. It also means that the interface name cannot
reliably be used to remove the directory - in fact the current code
doesn't even try, and always uses "wlan0"!
Since the name of a proc_dir_entry is embedded in it, use that when
removing it.
Add a netdev notifier to catch interface renaming, and remove and
re-add the directory at this point.

Currently, ramzwap devices (/dev/ramzswapX) can only
be used as swap disks since it was hard-coded to consider
only the first request in bio vector.
Now, we iterate over all the segments in an incoming
bio which allows us to handle all kinds of I/O requests.
ramzswap devices can still handle PAGE_SIZE aligned and
multiple of PAGE_SIZE sized I/O requests only. To ensure
that we get always get such requests only, we set following
request_queue attributes to PAGE_SIZE:
- physical_block_size
- logical_block_size
- io_min
- io_opt
Note: physical and logical block sizes were already set
equal to PAGE_SIZE and that seems to be sufficient to get
PAGE_SIZE aligned I/O.
Since we are no longer limited to handling swap requests
only, the next few patches rename ramzswap to zram. So,
the devices will then be called /dev/zram{0, 1, 2, ...}
Usage/Examples:
1) Use as /tmp storage
- mkfs.ext4 /dev/zram0
- mount /dev/zram0 /tmp
2) Use as swap:
- mkswap /dev/zram0
- swapon /dev/zram0 -p 10 # give highest priority to zram0
Performance:
- I/O benchamark done with 'dd' command. Details can be
found here:
http://code.google.com/p/compcache/wiki/zramperf
Summary:
- Maximum read speed (approx):
- ram disk: 1200 MB/sec
- zram disk: 600 MB/sec
- Maximum write speed (approx):
- ram disk: 500 MB/sec
- zram disk: 160 MB/sec
Issues:
- Double caching: We can potentially waste memory by having
two copies of a page -- one in page cache (uncompress) and
second in the device memory (compressed). However, during
reclaim, clean page cache pages are quickly freed, so this
does not seem to be a big problem.
- Stale data: Not all filesystems support issuing 'discard'
requests to underlying block devices. So, if such filesystems
are used over zram devices, we can accumulate lot of stale
data in memory. Even for filesystems to do support discard
(example, ext4), we need to see how effective it is.
- Scalability: There is only one (per-device) de/compression
buffer stats. This can lead to significant contention, especially
when used for generic (non-swap) purposes.

These checks are obviously pointless because kfree() can handle null
dereferences.
But really the main problem is that if the pointers were null that would
cause problems on the ealier lines. The dereferences would cause an
oops and the _release() functions use ->priv to determine which IRQ to
free. I looked into it and quite a few of the detach functions assume
link->priv is non-null. It seems like we can remove these checks.

Some comedi drivers should return an error from their 'open' method when
something goes wrong. Change the prototype of the 'open' method in
'struct comedi_device' to allow this, and change the drivers that use it.
Propagate any error to the 'open' file operation.
The corresponding 'close' method won't be called when the 'open' method
fails, so drivers failing the 'open' need to clean up any mess they
created.
The dt9812 and serial2002 drivers can now return an error on 'open'.
The jr3_pci driver also uses the 'open' method but doesn't fail it.

For write(), any data copied to the data buffer after the previously
set up streaming acquisition command has finished won't be used, but a
non-empty write() does not currently return 0 (or -EPIPE on error) after
the command has finished until the data buffer has been filled up.
Change this behavior to return 0 (or -EPIPE) any time after the command
has finished, without bothering to fill up the buffer with more useless
data.
