What: /sys/o2cb symlink
When: January 2010
Why: /sys/fs/o2cb is the proper location for this information - /sys/o2cb

linux/semaphore.h instead.

+---------------------------
+
+What: CONFIG_THERMAL_HWMON
+When: January 2009
+Why: This option was introduced just to allow older lm-sensors userspace
+ to keep working over the upgrade to 2.6.26. At the scheduled time of
+ removal fixed lm-sensors (2.x or 3.x) should be readily available.
