Shouldn't the kernel crash just by setting the avg_ms to 0 or do I
misunderstand the kernel commit changelog?

Or is the offending code that crashes the kernel invoked asynchronously
so that the value is picked up later by the scheduller? If so I would
prefer removing the sleep anyways since the test will fail if we happen
to be able to write 0 to the file anyways which is IMHO enough to inform
the user about the present bug.

Other than that the test looks fine.
