Question about "stateless or low-state functions" in KFuzzTest doc

[Jiakai Xu]

Hi Ethan and all,

I've been reading the KFuzzTest documentation patch (v4 3/6) with great 
interest. I have some questions about the scope and applicability of this 
framework that I'd like to discuss with the community.

The documentation states:
> It is intended for testing stateless or low-state functions that are 
> difficult to reach from the system call interface, such as routines 
> involved in file format parsing or complex data transformations.

I'm trying to better understand what qualifies as a "stateless or 
low-state function" in the kernel context. How do we define or identify 
whether a kernel function is stateless or low-state?

Also, I'm curious - what proportion of kernel functions would we 
estimate falls into this category?

Any insights would be greatly appreciated!

Thanks,
Jiakai
