This is common fair queuing code in elevator layer. This is controlled by config option CONFIG_ELV_FAIR_QUEUING. This patch initially only introduces flat fair queuing support where there is only one group, "root group" and all the tasks belong to root group. This elevator layer changes are backward compatible. That means any ioscheduler using old interfaces will continue to work. This is essentially a lot of CFQ logic moved into common layer so that other IO schedulers can make use of that in hierarhical scheduling setup.
