Zram currently uses LZO compression. With Snappy, it uses less CPU time and is
thus more useful. The sacrifice in compression ratio is small.
Zram's LZO and Snappy support can be independently enabled at compile time and
each zram device can switch between compression methods when unused.
When only a single compression method was enabled at compile time, no idirection
penalty is incurred.

Adding a new module that tracks the number of bytes/packets transfered by a network interface, even after the interface has been removed.
This is relevant to track the total data usage in mobile devices whose interfaces are added and removed quite frequently (WiFi, Bluetooth, 3G,..).
Monitoring is done only for devices that are configured with a valid IP address (check to exclude virtual/loopback/tunnel interfaces).

Included a little modification for the out-of-date HD2 .32 kernel.
- Now button backlight is managed by this driver, also it is configurable by sysfs (number of secs. after backlight will be turned off after last key-press, enable/disable this auto_off feature)
-When disabled auto_off, backlight will go off along with screen backlight.
- Sysfs for num. of seconds : /sys/devices/platform/btn_backlight_manager/off_seconds
(min: 5 sec, max: 60 sec)
- Sysfs for turn on/off auto-off feature: /sys/devices/platform/btn_backlight_manager/auto_off
(0 to disable auto-off, 1 to enable)
- remove all lights.*.so files from /system/lib/hw (backup if u want) and replace with lights.qsd8k.so from Bravo ROM or download from http://www.multiupload.com/2M5T02M3TU
- if button backlight don’t work: turn screen on, press any key and put phone under bright light ( this should activate light sensor and backlight)
