Probably should check out the wiki entry for the CFS Scheduler and all the associated references there.

Would you be willing to share credit?

Ask yourself - what is a scheduler? What makes an embedded system different from, say, a server or a desktop environment? What makes it special? Resources are limited, you might say. Processor would be underpowered. Maybe some processes need real time response. There are embedded systems and there are embedded systems. What you need is what you want. What you want is not what you sometimes get. What you want, sometimes you write yourself. Is CFS good or bad? Depends on what you use it for. Are there better scheduling algorithms available. Some might say yes.

Put forward a hypothesis and confirm or negate it with research. I suggest you start by looking at the scheduler code and how it is implemented in, for example, on android. I would imagine some benchmarking would be involved before you can come to a definite conclusion.
