H A D | neighbour.c | f618002b Wed Jan 22 00:53:33 CST 2014 viresh kumar <viresh.kumar@linaro.org> net/neighbour: queue work on power efficient wq
Workqueue used in neighbour layer have no real dependency of scheduling these on the cpu which scheduled them.
On a idle system, it is observed that an idle cpu wakes up many times just to service this work. It would be better if we can schedule it on a cpu which the scheduler believes to be the most appropriate one.
This patch replaces normal workqueues with power efficient versions. This doesn't change existing behavior of code unless CONFIG_WQ_POWER_EFFICIENT is enabled.
