wrq->name is only 16 characters long but "IEEE 802.11-MIMO" is 16 characters + a NULL character, so it's too long. This patch changes it to "IEEE 802.11abgn". Signed-off-by:

This doesn't change the behavior. It just silences a sparse warning. drivers/staging/wlan-ng/hfa384x_usb.c:2810:62: warning: dubious: !x | !y The point of the bitwise OR is so that a logical OR could short circuit the second call to test_and_set_bit(). Signed-off-by:

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.

These drivers use kzalloc() but don't include slab.h. They currently build though because the spi.h header will pull in slab.h for us. But rather than rely on that behavior forever, include slab.h explicitly. Signed-off-by:

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. Signed-off-by: -

Older mechanism of counting the number of protocols registered with ST was slow, in-efficient. It used to check the protocol data for NULL for each registration/unregistration.

Remove the older way of communicating with user-space daemon UIM. The older way involved creating of a new kobj and pid sysfs file under it, and sending signal using that pid. Now we communicate via rfkill to user-space UIM. Background: UIM is the user-space daemon which upon notification from ldisc driver, opens the tty, sets default baud and then installs (tiocsetd) the ldisc. Signed-off-by:
