-What: CONFIG_NF_CT_ACCT
-When: 2.6.29
-Why: Accounting can now be enabled/disabled without kernel recompilation.
- Currently used only to set a default value for a feature that is also
- controlled by a kernel/module/sysfs/sysctl parameter.
-Who: Krzysztof Piotr Oledzki <ole@ans.pl>

What: sysfs ui for changing p4-clockmod parameters
When: September 2009
Why: See commits 129f8ae9b1b5be94517da76009ea956e89104ce8 and
