Hmm, I do think the idea of a kernel test framework should be discussed in its own right.  I have implemented a much simpler one on my own for unit tests of locking primitives that you can see here.  These worked by declaring tests in linker sets in a kernel module.  Loading the module implicitly runs the tests.  I have other changes in this branch to allow "catching" panics like exceptions and similar changes for witness as well.

The test framework (much simpler) can be found at:

Sample test modules can be found here:

I think "test" is probably a better name for a subdir of test modules as it is more consistent with what we are doing in userland with kyua.
