This has been answered already.

This has been covered many times by the scheduler developers already.
With cgroups, you can do lots of neat things already, no need to change
any kernel code.

I do not think Coverity is doing anything with the kernel anymore.  But
we have lots of other good code coverage tools that do static analysis
that people are using, and fixing bugs with today (sparse, coccinelle,
etc.)

But this is a good one, I'll try to work it into the questions, thanks,
