o This is core of the io scheduler implemented at elevator layer. This is a mix of cpu CFS scheduler and CFQ IO scheduler. Some of the bits from CFS have to be derived so that we can support hierarchical scheduling. Without cgroups or with-in group, we should essentially get same behavior as CFQ. o This patch only shows non-hierarchical bits. Hierarhical code comes in later patches. o This code is the building base of introducing fair queuing logic in common elevator layer so that it can be used by all the four IO schedulers.
