@ -310,15 +310,6 @@ Who: Ravikiran Thirumalai <kiran@scalex86.org>
---------------------------
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.
Who: Rene Herman <rene.herman@gmail.com>
---------------------------
What: Code that is now under CONFIG_WIRELESS_EXT_SYSFS
(in net/core/net-sysfs.c)
When: After the only user (hal) has seen a release with the patches

If your machine is a loaded WEB server,
you should think about lowering this value, such sockets
