Re: [PATCH]RIFS-V3-Test For 3.4.x kernel.

[Chen <hi3766691@xxxxxxxxx>]

I haven't made any support for Cgroup yet. After I finished
translating the scheduler in modular form it will support Cgroup
naturally since the modular scheduler support Cgroup.

Anyway it is for desktop users and I don't think I  have to support
Cgroup in short term.

I am going to post the graphical benchmark between RIFS-V3-Test and
CFS. On my box, The latency of CFS is 8 times of RIFS
averagely.However I am not using my computer right now so I can't post
my benchmark now.
