Why: Over 1K .text/.data size reduction, data is available in other
ways (ioctls)
Who: Johannes Berg <johannes@sipsolutions.net>
---------------------------
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.

Those counters can be used for flow-based accounting or the

Please note that currently this option only sets a default state.
You may change it at boot time with nf_conntrack.acct=0/1 kernel
paramater or by loading the nf_conntrack module with acct=0/1.
You may also disable/enable it on a running system with:
sysctl net.netfilter.nf_conntrack_acct=0/1
